The Comprehensive Metabolic Panel (CMP) includes all 8 tests from the Basic Metabolic Panel plus 6 additional tests that evaluate liver function and protein levels. It provides a broad overview of your body's chemical balance and metabolism, making it one of the most informative routine blood tests available.
14 tests covering kidney function, liver function, electrolytes, blood sugar, and protein levels. The most-ordered panel in primary care.
Anyone doing an annual checkup, monitoring chronic conditions like hypertension or kidney disease, or starting a new medication that affects liver/kidney function.

14 biomarkers tested
Your Comprehensive Metabolic Panel results will include values for each of the 14 biomarkers tested, along with reference ranges. Results are reviewed by a licensed physician before being released to your secure portal.
If any values fall outside the normal range, your report will include guidance on what that may mean and recommended next steps. You'll receive an email notification when your results are ready, typically within 1–3 business days.
Typical reference range layout
Lab reports show where your value sits relative to established reference intervals—your physician interprets this in context for you.
Fasting for 10–12 hours is recommended for accurate glucose results. Water is okay.
The short answer
For most adults, yes. A CMP is one of the highest-value routine blood tests you can order - for under $30 it screens kidney function, liver function, blood sugar, and electrolytes in a single draw, which is why it is part of almost every annual physical.
We would rather you order the right test than the most expensive one.
A CMP needs a standard venous blood draw, so a fingerstick home kit will not work for it. Your two real options are walking into any Quest or Labcorp, or booking an at-home mobile phlebotomist where TestWell offers it. The sample and the results are identical either way - the lab, machines, and reference ranges are the same; only the convenience differs.
The markers that matter most and what an out-of-range value can mean. Reference ranges vary by lab, age and sex.
| Marker | Typical range | What it means |
|---|---|---|
| Glucose (fasting) | 70-99 mg/dL | 100-125 suggests prediabetes and 126+ suggests diabetes (on repeat); low readings usually reflect fasting or medication. |
| eGFR | 60 or higher mL/min | A calculated measure of kidney filtration; persistently under 60 points to reduced kidney function. |
| Creatinine | 0.6-1.3 mg/dL | High can mean the kidneys are working harder, or simply dehydration or high muscle mass. |
| ALT / AST | ~7-56 / 10-40 U/L | Liver enzymes; elevated levels flag liver inflammation from fatty liver, alcohol, or medications. |
| Albumin | 3.5-5.0 g/dL | A liver-made protein; low levels can reflect liver disease, kidney loss, or poor nutrition. |
| Calcium | 8.6-10.2 mg/dL | Out-of-range values can point to parathyroid, vitamin D, bone, or kidney issues. |

A Comprehensive Metabolic Panel test costs $22.99 at TestWell — $28.99 all-in when ordered alone, because the $6 lab processing fee is charged once per order, with no draw fee or physician fee added. Ordered directly from the labs' own consumer sites, the same test lists at $49.00 at Quest Health and $49.00 at Labcorp OnDemand (list prices checked Sep 12, 2026). Hospital outpatient labs typically bill around $200.00 self-pay for the same test, and often more. With insurance, what you pay depends on your deductible and your plan's negotiated rate; TestWell's price is fixed before the draw and is HSA/FSA-eligible. Full cost breakdown →
