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

  • The panel names its thyroid hormone and antibody measurements, but assay methods and analytical performance are not established for this exact bundle.
  • The five listed entries include a grouped thyroglobulin and thyroid peroxidase antibody pair. They are not a verified five-biomarker total or an exhaustive evaluation of thyroid function.
  • Results are emailed when available. Guided Optimization is a separate program with treatment eligibility requirements. An included consultation, individual interpretation service, actual sample report, reference-range explanation and follow-up plan have not been established for this test purchase.
  • Comparative value and clinical data or specimen privacy have not been fully assessed.
