About the Statin Check-Up Panel

Purpose of the test

The statin check-up panel evaluates how well your body is responding to treatment in lowering your LDL cholesterol and determines whether the statins are adversely affecting your liver and muscles.

For some individuals taking statins, blood sugar levels can increase, which may lead to type 2 diabetes, a risk significant enough that the FDA has issued a warning on statin labels. (Statin side effects: Weigh the benefits and risks – Mayo Clinic). Insulin resistance has also been noted with moderate to high doses of statins, but generally with those who already have higher glucose levels. According to Mayo Clinic’s overview of statin side effects, statins can also rarely cause liver inflammation (hepatotoxicity) or muscle breakdown. Intense muscle pain can be a symptom of rhabdomyolysis, a rare condition that causes muscle cells to break down. (Rhabdomyolysis from statins: What’s the risk? – Mayo Clinic) The panel may be helpful in the early identification of these conditions.

The panel doesn’t diagnose heart disease, measure plaque in your arteries, or replace imaging. While it does not specifically screen for diabetes, the glucose test (part of the CMP) and the included HbA1c can flag blood sugar changes for further evaluation.

The panel serves two purposes:

Screening: A baseline lipid and safety-marker check before starting a statin gives your provider a starting point. Evaluation may start earlier for youths with a family history of hypercholesterolemia or young adults with an LDL-C above 160 mg/dL.
Monitoring: The American Heart Association (AHA), along with professional organizations, recommends appropriate review to ensure adherence to therapy and that it is effectively addressing the reduction of LDL-C. This panel helps address this issue and the possible side effects of treatment. Under the 2026 ACC/AHA dyslipidemia guideline, a repeat lipid panel is typically done four to 12 weeks after starting or adjusting a statin, then at intervals your provider recommends.

What does the Statin Check-Up Panel measure?

The panel covers key markers to ensure treatment progress from a single sample at a CLIA-certified lab.

Metabolic Markers

Comprehensive Metabolic Panel (CMP): 14-component panel measuring:

Glucose: The amount of sugar in your blood at the time of the draw.
Calcium: Calcium circulating in your blood reflects bone and organ function.
Sodium: The main electrolyte controlling fluid balance outside your cells.
Potassium: The electrolyte that helps your heart and muscles contract properly.
Bicarbonate (CO2): Bicarbonate in your blood reflects acid-base balance.
Chloride: A key electrolyte that works with sodium to maintain fluid and acid-base balance.
Blood urea nitrogen (BUN): A waste product from protein breakdown, used to check kidney function.
Creatinine: A muscle waste product filtered by the kidneys, used to check kidney health.
Albumin: The main protein made by the liver, which carries nutrients and maintains fluid balance; reflects current liver function.
Total protein: The combined level of albumin and globulin proteins in your blood.
ALT (alanine aminotransferase): A liver enzyme that rises when liver cells are damaged or stressed.
AST (aspartate aminotransferase): A second liver enzyme used alongside ALT to check liver health.
ALP (alkaline phosphatase): An enzyme found in the liver and bones that can signal liver or bone disease.
Total bilirubin: The yellow pigment produced when red blood cells break down, processed by the liver.
HbA1c (a separately bundled marker): your average blood sugar over the past two to three months.

Complete Blood Count with Differential (CBC): 10-component panel measuring:

Red blood cell count (RBC): The number of red blood cells in a volume of blood.
White blood cell count (WBC): The total number of infection-fighting white blood cells.
Hemoglobin: The protein in red blood cells that carries oxygen throughout your body.
Hematocrit: The percentage of your blood volume made up of red blood cells.
Mean corpuscular volume (MCV): The average size of your red blood cells.
Mean corpuscular hemoglobin (MCH): The average amount of hemoglobin inside each red blood cell.
Mean corpuscular hemoglobin concentration (MCHC): The average hemoglobin concentration within red blood cells.
Red cell distribution width (RDW): Percent variation in red cell size.
Platelet count: The platelets that help form clots and stop bleeding.
White blood cell differential (neutrophils, lymphocytes, monocytes, eosinophils, basophils): The percentages of each of the five types of white blood cells, each having a specific function in responding to inflammation, infection, or other health issues.

Lipid Panel and additional lipid markers:

Total cholesterol: The overall amount of cholesterol in your blood.
HDL cholesterol: High-density lipoprotein, often called “good” cholesterol, which carries cholesterol away from arteries.
LDL cholesterol (LDL-C): Low-density lipoprotein, the “bad” cholesterol that is the primary target of statin therapy.
Triglycerides: A type of fat circulating in your blood that comes from food and is stored for energy use; high levels are associated with cardiovascular risk and can cause blood samples to be cloudy (lipemia), which then can interfere with other lab test results.
VLDL Cholesterol (VLDL): Very low-density lipoprotein, the cholesterol-carrying particle most closely tied to triglyceride levels.
Direct LDL Cholesterol (LDL): LDL cholesterol that is measured directly from the blood sample, used when triglycerides are too high for the standard calculation.

Complete Urinalysis (UA): 12-component panel measuring:

Color: The visible color of your urine, a basic indicator of hydration and health.
Appearance: Whether your urine is clear or cloudy, which can reflect cells or particles.
Specific gravity: How concentrated your urine is compared to pure water.
pH: The acidity or alkalinity of your urine; a high pH may indicate a urinary tract infection (UTI) or kidney issues, while a low pH is seen with diabetic ketoacidosis and diarrhea
Protein: Detects protein in urine, which isn’t normally present in significant amounts.
Glucose: Detects sugar in urine, which can appear when blood glucose is high.
Ketones: Detects ketone bodies, produced when the body burns fat for energy.
Occult blood: Detects blood in urine (hematuria) that may not be visible to the eye.
Leukocyte esterase: An enzyme released by white blood cells that can signal a urinary tract infection.
Nitrite: A chemical produced by certain bacteria, used as a marker for urinary tract infection.
Bilirubin: Detects bilirubin in urine, which can point to liver or bile duct problems.
Urobilinogen: A byproduct of bilirubin breakdown that can reflect liver function and red blood cell turnover.

Inflammation

High-Sensitivity C-Reactive Protein (hs-CRP): A protein that the liver releases in response to inflammation anywhere in the body. hs-CRP is more sensitive than a standard CRP, and can measure small but persistent increases in CRP as seen in cardiovascular disease (CVD).
Coenzyme Q10 (CoQ10): An antioxidant compound found in the mitochondria of all cells in the body and involved in energy production.

When should I get a Statin Check-Up Panel?

Consider testing if any of these apply:

Before starting statin therapy
A recent statin prescription or dose change within the past four to 12 weeks
Muscle pain, weakness, or tenderness since starting a statin
Unexplained fatigue or dark-colored urine while on a statin
A provider-ordered follow-up after a previous out-of-range lipid result
A family history of high cholesterol or early cardiovascular disease
Diabetes or metabolic syndrome alongside statin use
Annual or semi-annual monitoring as part of ongoing cardiovascular care

For routine monitoring, ACC/AHA guidance recommends:

Newly started on a statin: recheck lipids and liver enzymes four to 12 weeks after starting
After a dose change: recheck four to 12 weeks after the adjustment
On a stable regimen: recheck every three to 12 months, depending on your cardiovascular risk
Reporting muscle pain or weakness: get a CK test (creatine kinase) as soon as symptoms appear, not at your next scheduled visit. CK is an enzyme found in the heart muscle, skeletal muscle, and the brain. A CK blood test checks for any muscle damage or injury. If you are on statin therapy and experience any muscle cramping, pain, or weakness, a CK test may be ordered. Statins can sometimes cause muscle damage and, in rare cases, life-threatening muscle breakdown (rhabdomyolysis).

How It Works

How to get tested

Testing.com assembles this panel from individual Quest Diagnostics tests, combined into a single bundle.

This panel is ordered through a healthcare provider, clinic, or hospital lab. Your provider places the order with a CLIA-certified lab at a nearby patient service center or the provider’s in-office lab for the blood draw; results come back through the patient portal or office and are typically ready within one to three business days after the lab receives your sample, though timing can vary by lab.

Before the test

Fast for 9 to 12 hours before your draw. Water is fine. Fasting keeps your triglyceride levels accurate because the lab uses triglyceride levels to calculate your LDL cholesterol. The 2026 ACC/AHA dyslipidemia guideline recommends a fasting lipid panel four to 12 weeks after starting or adjusting a statin, then at intervals your provider recommends. (Guest Editorial: Clinicians Should Monitor LDL-C After Starting Lipid-Lowering Therapy | National Lipid Association Online) If triglycerides are falsely high from a recent meal, the LDL result won’t be reliable.

Skip food and caloric drinks for 9 to 12 hours. Water is allowed.
Avoid alcohol and high-fat meals the evening before. Both can raise triglycerides overnight.
Take your statin as prescribed on the morning of the test. The panel measures whether the medication is working at your usual dose. Skipping it would make LDL look lower than it normally runs, which could mask a needed dose change.
Avoid intense exercise for 24 hours before the draw. Hard workouts can temporarily raise creatine kinase (CK), which could be misread as a statin side effect. If a CK test is ordered, the National Library of Medicine notes that strenuous exercise is a common cause of temporary CK elevation.
Tell your provider about all medications and supplements. Other cholesterol-lowering drugs like fibrates, niacin, or ezetimibe, and herbal supplements like red yeast rice, can affect liver enzyme readings.

During the test

Bring a photo ID and your order confirmation. Check in at the patient service center.
A phlebotomist finds a vein in your arm, usually at the inside of the elbow. You’ll feel a brief pinch and mild pressure during the draw.
One or two tubes of blood are collected. The whole draw takes five to 10 minutes.
A small bandage covers the site. Keep it on for at least 15 minutes and avoid heavy lifting with that arm for a few hours.

Most people feel nothing after the draw. Light bruising over the next day or two is normal.

Don’t wait for your next scheduled test if you develop muscle pain, weakness, or dark-colored urine after starting or changing a statin. Contact your provider right away. These can be early signs of myopathy.

After the test

Results are typically ready within one to three business days after the lab receives your sample, though timing can vary by lab. They’ll come through your ordering provider’s patient portal or office. Some providers review results before releasing them. If you don’t see results within three business days, call the provider’s office.

What Do My Results Mean?

Your results show two things: whether each biomarker falls within a healthy range, and whether your LDL cholesterol has reached the ACC/AHA target for your risk category. Reference ranges vary slightly between labs. Your provider reads your results in the context of your full cardiovascular history, not the numbers alone. The American College of Cardiology (ACC) and the American Heart Association (AHA) have set guidelines to prevent a first heart attack or stroke: those who are borderline or at intermediate risk should have an LDL-C level less than 100 mg/dL, and for high-risk individuals, the goal is less than 70 mg/dL. And the goal for very high-risk individuals with ASCVD (atherosclerotic cardiovascular disease) is less than 55 mg/dL.

Biomarker

Standard Reference Range

Total Cholesterol

Less than 200 mg/dL (desirable)

LDL Cholesterol

Less than 100 mg/dL (optimal)

HDL Cholesterol

Men: 40 mg/dL or higher; Women: 50 mg/dL or higher

Triglycerides

Less than 150 mg/dL

ALT

7 to 56 U/L (lab-dependent)

AST

10 to 40 U/L (lab-dependent)

HbA1c

Less than 5.7% (non-diabetic)

hs-CRP

Less than 1.0 mg/L (low cardiovascular risk)

Ranges are approximate and vary by lab. If triglycerides exceed 400 mg/dL, the lab uses a direct LDL measurement because the standard Friedewald calculation isn’t reliable at that level. (MDCalc: Friedewald LDL-C calculator)

If your results are within range

LDL-C has reached your ACC/AHA target. The statin may be working as intended. If liver enzymes (ALT and AST) are within range, it means statin-related liver stress has been avoided. If HbA1c is within range, it means blood sugar is under control. Schedule your next check per your provider’s guidance, typically every three to 12 months based on your cardiovascular risk, and keep up the habits that support the result.

If your results are out of range

LDL still above target: The statin may not be at the right dose, or dietary factors may be blunting the effect. Your provider may adjust the dose, switch statins, add ezetimibe or a PCSK9 inhibitor, or look at adherence and diet. Don’t adjust your medication on your own.

High ALT or AST: Occasionally, statin use causes an increase in liver enzymes. If the increase is mild, you can continue to take the medicine. Low to moderate doses of statins don’t appear to raise liver enzyme levels severely. (Statins: Are these cholesterol-lowering drugs right for you? – Mayo Clinic) Your provider will likely recheck in a few weeks. If ALT and/or AST levels rise above three times the upper limit of normal, your provider will probably pause or switch the statin therapy to allow the liver to recover. If there are signs of jaundice, fatigue, nausea, or dark urine, the statin should be immediately stopped. Enzyme levels need to be rechecked before restarting.

High CK: Mild elevation (less than four times the upper limit of normal) with no symptoms is usually monitored, but not acted on right away. If CK is 10 times the upper limit of normal, especially if you have symptoms of rhabdomyolysis, stop taking your statin and seek medical treatment right away, as your provider can take steps to help prevent kidney damage and other complications.

Triglycerides above 400 mg/dL: Your LDL-C result may not be reliable due to the fatty consistency (triglycerides) of your blood that interferes with the test. Your provider will interpret with caution or order a direct LDL cholesterol test instead. The National Library of Medicine’s lipid panel explainer notes that very high triglycerides can interfere with standard LDL calculation methods.

FAQs

Should I take my statin the morning of the test?

Yes. Take it as prescribed. The panel measures whether the medication is working at your usual dose. Skipping it could make your LDL look falsely lower than it actually is, which might hide a needed dose change.

What's the difference between a statin check-up panel and a standard lipid panel?

A standard lipid panel measures total cholesterol, LDL-C, HDL-C, and triglycerides. A statin check-up panel adds liver enzymes (ALT, AST), HbA1c, hs-CRP, CoQ10, a complete blood count, a full metabolic panel, and a urinalysis to screen for medication side effects and broader health markers. The standard panel alone doesn’t include safety monitoring.

What's the difference between LDL cholesterol and LDL particle number?

LDL cholesterol (LDL-C) measures the amount of cholesterol carried by LDL particles. LDL particle number (LDL-P) counts the actual particles in the blood. Some people have normal LDL-C but a high LDL-P, which still raises cardiovascular risk. LDL-P requires a separate NMR (nuclear magnetic resonance) test.

What should I do if I have muscle pain while taking a statin?

Contact your provider before your next scheduled test. Muscle pain, weakness, or tenderness on a statin can signal myopathy. Your provider may order a CK test right away. Don’t stop the statin without talking to your provider first.

How often should I get a statin check-up panel?

The 2026 ACC/AHA dyslipidemia guideline recommends a repeat lipid panel four to 12 weeks after starting or adjusting a statin. Once the dose is stable and LDL-C is at target, most providers recheck every three to 12 months. Your provider sets the exact schedule based on your risk and how well the medication is working.

Does the statin check-up panel test for diabetes?

Yes. The panel includes HbA1c, which reflects your average blood sugar over the past two to three months. Statins can raise blood sugar, which may lead to type 2 diabetes, so HbA1c helps your provider watch for that effect alongside your lipid results.

Can I get this panel without a provider visit?

Some CLIA-certified labs allow testing without a prior provider appointment. But reading the results, especially statin-specific LDL targets and liver enzyme thresholds, requires clinical context. A provider visit before or after the test helps make sure results are interpreted correctly for your risk category.
