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.

Important limits and omissions

  • Exact offer page names no performing laboratory and no assay method; Quest Diagnostics appears only as brand metadata, not as a named testing route for this exact offer.
  • Page hero shows a 'Test Today for $1, Pay Balance After Results' promotion; rendered hero after-results amount differs from the authoritative Offer JSON-LD price; price taken from exact-product JSON-LD.
  • Provider-wide testing limits: tests are not available in NY, NJ, RI per provider policy; exact per-offer state list is not published.
  • Product-specific HSA and FSA eligibility or reimbursement is not confirmed; the provider documents payment-card acceptance only.
  • The provider privacy notice does not publish a fixed data-retention period.
  • Refunds are limited to the period before specimen submission, with no refund after 21 days. The money-back guarantee is conditional.
  • The exact offer does not publish a complete assay-method and analytical-performance description.

The full breakdown

Eight Dimensions.
One Named Result.

Open any row for the reasoning and evidence behind the named result.

The offer names thyroid stimulating hormone and free T4 measured by direct dialysis. The exact performing laboratory is chosen during ordering from the Quest Diagnostics or Labcorp route and is not identified on the offer page, so independent verification of the assays is not confirmed.

The offer positions this test for people with unexplained fatigue, weight changes, mood swings, or temperature sensitivity. TSH shows how hard the pituitary is driving the thyroid while free T4 shows the active hormone available in blood; whether the results can diagnose a condition is not established.

The offer lists two markers: TSH and free T4. It does not include T3 markers or thyroid antibodies, and no comparison against any clinical guideline is provided on the offer page.

Results arrive by email and SMS with normal ranges explained, plus doctor notes in plain language and a downloadable standard lab report. The offer page shows illustrative sample results with reference ranges. Guidance on measurement uncertainty and when to seek care beyond the notes is not detailed.

Private MD Labs creates the physician lab order remotely and states that the prescription and all lab fees are included. The lab company, Quest Diagnostics or Labcorp, is selected during ordering; the exact performing laboratory is not named on the offer page.

Ordering is online and the blood draw happens at a lab visit across about 4,000 locations; most locations do not accept walk-ins, so booking ahead is advised. Direct-access testing is unavailable in HI, NJ, NY, and RI. No fasting is required, samples should not be collected during or soon after Heparin use, and the offer page states results are typically available within 7 business days.

The offer page shows a price of 72 USD. Services are strictly self-pay and cannot be billed to health insurance, though HSA and FSA payments are accepted. The page describes a money-back guarantee for first-time customers who file within 15 days of receiving results, and orders can be cancelled before samples are collected.

The provider states HIPAA compliance and that it does not sell or share customer data. Results are delivered to a secure online account with email and SMS notification. No fixed data-retention period is published on the offer page.

The balance

The Strengths. The Tradeoffs.

Strengths

  • Documents thyroid-stimulating hormone and free T4 by direct dialysis.
  • Complete results are listed within 7 business days; confirmation testing may extend the estimate. The retained source instructs that samples should not be collected during or soon after heparin administration.
  • The exact offer page and purchase state document a current price of $72 USD.
  • Private MD Labs arranges the physician lab order, so buyers do not need to supply their own clinician.
  • Results are delivered digitally with report context documented for this exact offer.
  • The privacy notice allows account and data deletion requests, subject to regulatory, compliance, legal, and business retention requirements.

Watch-outs

  • Product-specific validation, precision, interference, and quality-control evidence are not fully established.
  • Abnormal results require clinical interpretation and do not establish a diagnosis from this panel alone.
  • HSA and FSA card acceptance is documented, but eligibility or reimbursement for this exact offer is not confirmed.
  • Refunds are permitted only before specimen submission and are unavailable after 21 days from payment. The 90-day money-back guarantee has first-customer, result, and test-category conditions.
  • The privacy notice permits defined laboratory and service-provider disclosures, deidentified research use with an opt-out, and third-party advertising unless the user opts out. No fixed retention period is published.
  • Private MD Labs does not offer services to residents of New York, New Jersey, or Rhode Island. Exact collection-site availability should be checked before purchase.
