About the Essential Health Panel
Purpose of the test
The essential health panel gives you and your provider a broad snapshot of metabolic health, blood cell function, cardiovascular risk, thyroid status, and nutritional markers from a single blood draw and urine sample. It serves as a preventive assessment of your current health status that takes into account lifestyle habits and any potential risk areas that would require follow-up.
The panel may indicate the presence of several common conditions: heart disease, type 2 diabetes, prediabetes, kidney disease, liver disease, anemia, thyroid disorders, and electrolyte imbalances. High cholesterol often shows no symptoms, but the resulting plaque buildup can. Most people with prediabetes generally don’t show symptoms, but may experience some as they move to type 2 diabetes. Kidney or liver disease initially shows no symptoms, but gradually, signs such as fatigue, nausea, and loss of appetite, become evident. That’s why a panel like this can catch problems before you’d ever notice them.
The panel serves three purposes:
- Screening: The American Heart Association (AHA), American Diabetes Association (ADA), and other major health organizations recommend screening adults for cardiovascular, metabolic, and kidney/liver risks before symptoms appear.
- Diagnosis: Consider testing if you have fatigue, unexplained weight changes, increased thirst, or frequent urination that may point to a metabolic or blood disorder.
- Monitoring: Track known conditions like prediabetes, high cholesterol, or kidney disease and see how well lifestyle changes or medications are working.
One thing to know upfront: “essential health panel” isn’t a single standardized product. One lab’s version may include thyroid function and vitamin D. Another may include only the core metabolic and blood markers. Review the included sub-panels before your draw and ask your provider if specific markers are missing.
This panel does NOT cover STI screening, cancer markers, or drug and pregnancy testing. The urinalysis component isn’t a drug test or pregnancy test.
What does the Essential Health Panel measure?
The essential health panel covers 10 sub-panels and markers from a single blood and urine sample at a CLIA-certified lab.
Metabolic Markers
Comprehensive Metabolic Panel (CMP): 14-component panel measuring:
- Glucose: The primary sugar in your blood, used to screen for diabetes and monitor blood sugar.
- Calcium: A mineral that supports bone strength, muscle function, and nerve signaling.
- Sodium: An electrolyte that helps regulate fluid balance and supports nerve and muscle function.
- Potassium: An electrolyte essential for muscle function, nerve signaling, and moving nutrients into cells.
- Bicarbonate (CO2): A form of carbon dioxide that helps maintain your body’s acid-base balance.
- Chloride: An electrolyte that works with sodium to regulate fluid levels and acid-base balance.
- Blood urea nitrogen (BUN): A waste product from protein breakdown that your kidneys filter from the blood.
- Creatinine: A muscle waste product filtered by the kidneys, used to check how well they’re working.
- Albumin: The main protein in your blood that is made by your liver; it maintains fluid balance, transports hormones and vitamins, and aids in tissue repair, reflecting liver function and nutritional status.
- Total protein: The combined amount of albumin and other proteins in your blood, reflecting liver function and overall nutritional status.
- ALT (alanine aminotransferase): A liver enzyme that rises when liver cells are damaged or inflamed.
- AST (aspartate aminotransferase): An enzyme found mainly in the liver, with small amounts in the heart, muscles, kidneys, and pancreas; an elevated level most often indicates liver damage or inflammation.
- ALP (alkaline phosphatase): An enzyme linked to liver and bone health, often checked alongside other liver markers.
- Total bilirubin: A waste product made when the liver breaks down old red blood cells.
Hemoglobin A1c (HbA1c): Measures your average blood sugar over the past eight to 12
weeks, unlike fasting glucose, which only captures the amount of glucose at the time of the blood draw.
Gamma-Glutamyl Transferase (GGT): A liver enzyme that protects your cells from damage; alcohol, certain medications, and liver, pancreas, or heart conditions can elevate GGT levels.
Complete Blood Count with Differential (CBC): 10-component panel measuring:
- Red blood cell count (RBC): The total number of red blood cells, which carry oxygen throughout your body.
- White blood cell count (WBC): The total number of white blood cells, your body’s main defense against infection.
- Hemoglobin: The oxygen-carrying protein inside red blood cells, measured to screen for anemia.
- 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, which helps identify the type of anemia.
- Mean corpuscular hemoglobin (MCH): The average amount of hemoglobin inside each red blood cell.
- Mean corpuscular hemoglobin concentration (MCHC): The average hemoglobin concentration within a given volume of red blood cells.
- Red cell distribution width (RDW): How much your red blood cells vary in size.
- Platelet count: The number of platelets, the cell fragments that help your blood clot.
- White blood cell differential (neutrophils, lymphocytes, monocytes, eosinophils, basophils): The percent of each white blood cell type, showing which part of your immune system is most active.
Lipid Panel: 5-component panel measuring:
- Total cholesterol: The combined amount of all cholesterol types in your blood.
- HDL cholesterol: High-density lipoprotein (HDL), the “good” cholesterol that carries LDL away from your arteries.
- LDL cholesterol: Low-density lipoprotein (LDL), the “bad” cholesterol that can build up in artery walls to form plaques and raise the risk of heart disease.
- Triglycerides: A type of fat in your blood that comes from food and is stored for energy use; high levels are associated with cardiovascular risk.
- VLDL Cholesterol (VLDL): Very low-density lipoprotein (VLDL) cholesterol is a fat-carrying particle that transports triglycerides through the blood.
Complete Urinalysis (UA): 12-component panel measuring:
- Color: A visual check that can reflect hydration and certain health conditions.
- Appearance: Whether your urine is clear or cloudy, which can signal infection or other issues.
- Specific gravity: A measure of urine concentration that helps check hydration.
- pH: How acidic or alkaline your urine is; a high pH may indicate a urinary tract infection (UTI) or kidney issues, while a low pH is seen with diabetic issues and diarrhea.
- Protein: Detects mainly albumin in urine, which can signal kidney stress or damage when high.
- Glucose: Checks for sugar in urine, which can appear when blood sugar is high.
- Ketones: Compounds your liver makes when your body burns fat for fuel instead of glucose.
- Occult blood: Microscopic blood in urine (hematuria) that isn’t visible to the naked eye.
- Leukocyte esterase: An enzyme released by white blood cells in urine, pointing to possible infection or inflammation.
- Nitrite: Byproducts from certain bacteria in the urinary tract, suggesting a possible infection.
- Bilirubin: A liver waste product that isn’t normally present in urine in significant amounts.
- Urobilinogen: A byproduct of bilirubin breakdown that passes through the liver and into urine.
Thyroid
- Thyroid Stimulating Hormone (TSH): The hormone that signals your thyroid gland to produce hormones that control metabolism, energy, heart rate, and digestion; used to screen for an overactive or underactive thyroid.
Nutritional Markers
- Vitamin D, 25-Hydroxy, Total: The main form of vitamin D stored in your body, reflecting your overall vitamin D status.
- Iron, Total: The amount of iron circulating in your blood that is needed to make hemoglobin in red blood cells; most often used to screen for iron deficiency. Excess iron can occur from conditions of liver disease, alcohol use, or repeated blood transfusions. Most do not show any symptoms. A genetic form, hereditary hemochromatosis, is seen in about 1 in 300 non-Hispanic White Americans.
When should I get an Essential Health Panel?
Consider testing if any of these apply:
- Fatigue or low energy without a clear cause
- Family history of heart disease, diabetes, or kidney disease
- Increased thirst or frequent urination
- No recent comprehensive blood work or established baseline
- Known risk factors for cardiovascular or metabolic disease
- Provider recommendation for annual labs
- Unexplained weight gain or loss
For routine screening, major health organizations offer specific guidance:
- The AHA recommends cholesterol screening beginning at age 30 for most adults, and earlier for those with risk factors, as part of updated ACC/AHA dyslipidemia guidelines.
- The ADA recommends testing for prediabetes or type 2 diabetes in adults of any age who are overweight or obese (BMI ≥25, or ≥23 for Asian Americans), have one or more other risk factors (high blood pressure, family history of diabetes, low HDL or high triglycerides, or PMOS, formerly PCOS). For all other people, screening should begin at age 35. In people without prediabetes or diabetes after screening, repeat screening at a minimum of three-year intervals is reasonable, sooner if symptoms appear or there is a change in risk. Those already diagnosed with prediabetes should be tested annually.
- The National Heart, Lung, and Blood Institute (NHLBI) recommends lipid screening every five years beginning at age 20. Any abnormalities require follow-up. Those with familial hypercholesterolemia, a genetic disorder that causes very high LDL, should begin screening as early as age 2, with periodic follow-up.
- Primary care providers commonly order annual comprehensive labs for adults 40 and older.
- Adults managing high blood pressure, obesity, or prediabetes benefit from more frequent monitoring.
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 health care provider, clinic, or hospital lab. CLIA-certified labs process most panels of this type across the U.S.
Here’s the typical process: your provider orders the panel, you visit a nearby patient service center for a blood draw and urine collection, and results come back through the provider’s patient portal or office. You don’t need a separate appointment for each sub-panel. Everything runs from the same samples collected in one visit.
Before the test
Fast for 12 hours before your appointment. Water is fine. Fasting matters most for glucose and triglyceride accuracy. Your CBC and most kidney and liver markers aren’t fasting-sensitive. Inform your provider or phlebotomist if you have not fasted.
Consult your provider as to whether you should avoid taking any dietary supplements, such as biotin (vitamin B7, also found in hair, skin, and nail products), vitamin C, iron tablets, or creatine supplements at least 72 hours before the draw. Biotin can interfere with immunoassay-based tests and cause falsely high or low results for certain markers, including thyroid tests. The FDA has warned that biotin can interfere with certain lab tests. Other supplements can also affect test results, which can lead to diagnosis errors, missed conditions, or unnecessary additional follow-up.
Tell your provider about all medications and supplements before the draw. Don’t fast if you have diabetes or a condition that makes fasting unsafe. Ask your provider how to handle prep in that case.
During the test
- Bring a photo ID and any paperwork from your provider. Check in at the patient service center.
- A phlebotomist ties a tourniquet around your upper arm, cleans the skin, and draws blood from a vein. You’ll feel a brief pinch.
- If the urinalysis is included, you’ll collect a urine sample in a clean cup in a private restroom. No special prep is needed beyond the fasting window.
- A small bandage covers the draw site. Keep it on for at least 15 minutes to ensure bleeding has stopped
The whole visit takes about 15 to 30 minutes. Some people feel lightheaded after a blood draw, especially after fasting. Sit for a few minutes before you leave if you feel unsteady.
Light bruising at the draw site over the next day or two is normal. Call your provider if you have lasting pain, swelling, or signs of infection.
After the test
Results are typically ready one to four business days after the lab receives your sample, though timing can vary by lab. You’ll usually get them through your provider’s patient portal or a call from the office.
Some out-of-range results may prompt a call before you log in to check. Don’t wait if you have questions.
What Do My Results Mean?
The essential health panel returns separate results for each sub-panel, not a single pass/fail score. Reference ranges vary slightly between labs, and your report will flag values outside the normal range.
How your provider reads results depends on context: your fasting status, current medications, age, and existing conditions all play a role. The table below shows general ranges for key markers.
| Sub-Panel | Key Marker | General Normal Range |
| CMP, Glucose (fasting) | Blood sugar | 70–99 mg/dL |
| CMP, Creatinine | Kidney waste marker | 0.6–1.1 mg/dL (women); 0.7–1.2 mg/dL (men) |
| CMP, ALT | Liver enzyme | 7–56 U/L |
| CBC, Hemoglobin | Oxygen-carrying protein | 12.0–15.5 g/dL (women); 13.5–17.5 g/dL (men) |
| Lipid, LDL Cholesterol | “Bad” cholesterol | Less than 100 mg/dL (optimal) |
| Lipid, HDL Cholesterol | “Good” cholesterol | 50+ mg/dL (women); 40+ mg/dL (men) |
| Lipid, Triglycerides | Blood fats | Less than 150 mg/dL |
| HbA1c | Average blood sugar (eight to 12 weeks) | Below 5.7% (normal); 5.7–6.4% (prediabetes); 6.5%+ (diabetes) |
| TSH | Thyroid function | Approximately 0.4–4.0 mIU/L (varies by lab) |
Ranges are approximate and vary by lab. Your report will show the reference range used.
If your results are within normal range
All markers within the lab’s reference ranges give you a solid baseline. But normal results don’t rule out conditions the panel doesn’t measure. STIs, most cancers, and specific vitamin deficiencies other than vitamin D or iron won’t show up here.
Share your results with your provider to discuss trends over time, especially if this is your first comprehensive panel. If results look normal but symptoms persist, follow up about additional testing.
If your results are outside the normal range
One abnormal marker doesn’t mean a diagnosis. Context matters. Here’s what the major out-of-range patterns often prompt:
- High LDL or triglycerides: Discuss cardiovascular risk with your provider. Lifestyle changes and medication are both on the table.
- Fasting glucose 100–125 mg/dL, or HbA1c 5.7–6.4%: These ranges indicate prediabetes, according to the American Diabetes Association’s diagnosis criteria. Lifestyle changes and retesting in three to six months are typical next steps.
- HbA1c at 6.5% or higher: Your provider will likely confirm with a repeat test before diagnosing diabetes.
- Low hemoglobin or high WBC: Follow-up testing often looks at anemia, infection, or inflammation.
- High ALT or AST: Your provider may ask about alcohol use, medications, or supplements. Further liver testing may follow.
- High creatinine or low eGFR: A follow-up kidney function panel is often the next step.
The panel gives data, not a diagnosis. Your provider reads results alongside your full health history.
