A comprehensive metabolic panel, a CBC with differential and hs-CRP in one draw — the nine results the PhenoAge model needs. Your biological age, the gap to your calendar age and what moved it appear on your results page automatically. Biological age is an estimate of how your body's routine blood markers compare with people of different ages. This panel collects the nine the PhenoAge model (Levine 2018) uses — albumin, creatinine, glucose and alkaline phosphatase from the metabolic panel; white cells, lymphocyte percentage, MCV and RDW from the blood count; and high-sensitivity CRP — and TestWell calculates the result for you. On your results page you see your phenotypic age ("your markers look like a typical 42-year-old's"), the difference from your calendar age, a likely range, and which markers are pulling the number up or down, alongside the 30-plus individual results a CMP, CBC and hs-CRP report on their own: kidney and liver function, blood sugar, electrolytes, red and white cells, platelets, and inflammation. The useful read is the trend: re-draw the same panel in 3–6 months at the same lab and watch which way the number moves. It is a wellness estimate from a population model, not a diagnosis, and it does not measure your cells or your DNA. **Clinical use:** General health testing provides a baseline snapshot of organ function, metabolism, and key biomarkers — useful for annual checkups, preventive care, and tracking changes over time. ## Who should order it? Adults wanting a routine wellness baseline, anyone re-engaging with healthcare after a gap, and people tracking the impact of lifestyle or medication changes. ## Tests included | Test | Biomarkers | Standalone price | CPT | | --- | --- | --- | --- | | [Comprehensive Metabolic Panel](https://www.test-well.com/tests/comprehensive-metabolic-panel) | 14 (Glucose, BUN, Creatinine, Sodium, Potassium, Chloride, …) | $22.99 | 80053 | | [CBC with Differential](https://www.test-well.com/tests/cbc-with-differential) | 14 (WBC, RBC, Hemoglobin, Hematocrit, MCV, MCH, …) | $21.99 | 85025 | | [Heart & Body Inflammation Test (hs-CRP)](https://www.test-well.com/tests/hs-crp) | 1 (hs-CRP) | $34.99 | 86141 | ## Price by lab | Lab | Panel price | All-in (with $6 fee) | Notes | | --- | --- | --- | --- | | Quest Diagnostics | $59.99 | $65.99 | Choose at checkout | | Labcorp | $59.99 | $65.99 | Choose at checkout | | BioReference (NY & NJ) | $59.99 | $65.99 | New York and New Jersey orders route here automatically | ## How much does a Biological Age Panel cost? A Biological Age Panel costs $59.99 at TestWell — $65.99 all-in, since the $6 lab processing fee is charged once per order and there is no draw or physician fee. With insurance you pay your plan's negotiated rate against your deductible; TestWell's price is fixed before the draw and HSA/FSA-eligible. | Where you order | Price | One test, all-in | Notes | | --- | --- | --- | --- | | TestWell (drawn at Quest or Labcorp) | $59.99 | $65.99 | Includes the one $6 lab processing fee, charged once per order | ## How do you prepare? Fast for 10–12 hours before the draw (water is fine) so the glucose result is a fasting value. Draw when you are well — a cold, a recent injury or a hard workout the day before raises hs-CRP and white cells and adds years to the estimate. A morning draw is easiest to repeat. ## Related conditions - Routine health screening (Z00.00) ## Common questions about the Biological Age Panel ### What tests are included in the Biological Age Panel?

Prednisone and other corticosteroids, exercise and dehydration can change a Biological Age Panel result without anything being wrong. Prednisone and other corticosteroids can raise Glucose and WBC and can lower Lymphocytes, hs-CRP and Potassium — expected on steroids; A1c over weeks reflects it. Exercise can raise ALT and Creatinine and 2 more markers on this test — rest 48 hours before a liver panel. Dehydration can raise BUN and Hemoglobin and 2 more markers on this test — hydrate normally; water is allowed during a fast. Each is explained on our physician-reviewed "Before your test" pages; when one applies, remove it and retest. ## How to order 1.
