The Test Grade. The Reason Behind It.

Potentially useful for the right buyer, with meaningful evidence, coverage, transparency, access, cost, terms, or privacy tradeoffs to review.

A lower grade does not mean a panel is a bad personal fit. Your Fit Score can be higher when its purpose, price, sample, access, or support matches what you need.

Confirmed

Visit the selected Labcorp location for a serum blood draw. Test 146688 requests 1 mL serum, minimum 0.8 mL without enough for repeat testing, in a red-top or gel-barrier tube. Separate serum into a plastic transport tube if red-top is used. Store at room temperature. Plasma is rejected. This is not a home kit. Mito recommends a morning draw before 10 a.m. and does not require fasting. Report hormonal medicines, acute illness and recent intense exercise. Labcorp requests age and sex and warns about high-dose biotin interference, with at least 72 hours without biotin before collection; confirm instructions with your clinician and do not stop prescribed treatment on your own.

The balance

The Strengths. The Tradeoffs.

Strengths

  • Online ordering includes the required laboratory order through Mito.
  • Measures total testosterone and SHBG and calculates the Free Androgen Index from their ratio in matching units, multiplied by 100. The index is not a direct free-testosterone measurement. Albumin, directly measured free testosterone and bioavailable testosterone are not included.
  • Results are delivered to the Mito dashboard after laboratory processing.

Watch-outs

  • Available in 47 states and Washington, DC. Not currently available in NJ, NY or RI.
  • Labcorp test 146688, for 47 states and Washington, DC, excluding NJ, NY and RI: $16.64 without membership or $11.88 with optional $9 monthly membership, plus a separate $11.50 order fee.
  • Membership is optional. The final checkout total, cancellation and refund terms remain unverified.
  • Typical results take 1-2 days; this is not a guaranteed order-to-result deadline.
  • FAI is a calculated estimate, not a measured free-testosterone concentration or a diagnosis. SHBG changes can affect interpretation; use the laboratory reference range and clinical context rather than treating the index as interchangeable with direct free or bioavailable testosterone.
  • Mito recommends a morning draw before 10 a.m. and does not require fasting. Report hormonal medicines, acute illness and recent intense exercise. Labcorp requests age and sex and warns about high-dose biotin interference, with at least 72 hours without biotin before collection; confirm instructions with your clinician and do not stop prescribed treatment on your own.
  • Results appear in the Mito dashboard after laboratory processing. A personalized action plan requires membership; live consultations cost extra.
  • This test is marked HSA/FSA eligible. Your plan determines individual eligibility and reimbursement.
