| hs-CRP hs-CRP measures inflammation at a much finer level than standard CRP. It’s designed to detect low-grade, chronic inflammation often linked to cardiovascular risk, recovery capacity, and long-term health. Ideal for athletes tracking recovery, metabolic health, or cardiovascular performance. | Inflammation & Immune Markers | Quest | $18 |
| T4 Free (FT4) This test measures the unbound, biologically active form of thyroxine (T4) circulating in the blood. Unlike total T4, it reflects the portion not attached to proteins and available for use by tissues. Free T4 is a key marker of thyroid function and helps assess how much hormone is available to act on the body. | Thyroid Function | Quest | $17 |
| Dihydrotestosterone (DHT) This test measures the amount of dihydrotestosterone (DHT) in your blood. DHT is made from testosterone and is one of the most powerful androgens (male hormones). It plays an important role in things like muscle development, hair growth, and prostate health. Why it Matters Checking DHT levels can help your provider understand issues like hair loss, unwanted hair growth, acne, prostate concerns, or symptoms of low testosterone. It’s also useful if you’re taking medications that block DHT (like finasteride or dutasteride) to be sure they’re working as intended. Advanced Accuracy This test is performed using LC/MS/MS (liquid chromatography–tandem mass spectrometry). That’s a state-of-the-art method that’s more precise than standard hormone tests, so even very small amounts of DHT can be measured accurately. | Hormones | Quest | $54 |
| Copper, RBC Copper, RBC measures the concentration of copper within red blood cells. Unlike serum copper, which reflects short-term dietary intake, the RBC copper test gives a better picture of long-term copper status at the cellular level. Copper is an essential trace mineral involved in energy production, nervous system function, immune defense, and the formation of connective tissue. It also plays a role in iron metabolism and the synthesis of hemoglobin. | Blood & Iron Markers | Quest | $30 |
| Methylenetetrahydrofolate Reductase (MTHFR), DNA The MTHFR (methylenetetrahydrofolate reductase) gene helps your body process folate and regulate homocysteine levels. Variations in this gene may affect methylation, cardiovascular health, fertility, and how your body uses certain nutrients. This test looks for the most common MTHFR variants (C677T and A1298C) to help you understand your genetic profile and whether additional lifestyle, dietary, or supplement support may be beneficial. | Individual Lab | Quest | $175 |
