Who should buy which

Pick the Everlywell Thyroid Test if

Anyone who wants a fuller thyroid read than a TSH-only test before a doctor visit, or who tracks thyroid markers over time and wants a repeatable at-home baseline.

Skip if

You need a clinical diagnosis, a same-day result, or you want a venous draw with a broader metabolic panel. This is a four-marker screening test, not a full workup.

Pick the SiPhox Health At-Home Biomarker Test if

Buyers who want frequent, low-friction biomarker tracking without lab visits or needles, especially anyone testing quarterly to watch trends rather than once a year. HSA/FSA users get a meaningful pre-tax discount.

Skip if

You want the single broadest one-time panel (Function 160+ or Mito 117 to 178 markers with clinician review), or you need an active prescribing relationship for hormones or GLP-1s - this is testing and insight only.
