Best blood tests for women.

Function Health is the U.S. subscription wellness-testing leader in 2026 and the most defensible buy in the comprehensive tier. The pitch — two annual venous draws, 110-plus markers, MD review on every result, and a dashboard that tracks numbers over time — is genuinely category-defining. The $499 annual price feels high until you compare it to what comprehensive lab work plus an MD interpretation costs out-of-pocket.

What we like: the breadth of the panel is the only one in the category that approaches what a proactive primary care doctor would order. The dashboard is the best in the U.S. at translating numbers into plain-English. The MD review is a real review — not a templated PDF — and Function will surface what to focus on first when you have a wall of flagged numbers.

What we do not like: the subscription only makes sense if you will actually use it twice a year. If you want one comprehensive panel and never repeat it, you can do better on price elsewhere. Some venues are also limited — confirm draw locations near you before paying.

Best for: women who want comprehensive wellness data as a yearly habit, the optimization-minded reader, and women without a primary care provider running comprehensive preventive labs in their 30s and 40s. Worth discussing results with a qualified healthcare provider.

LetsGetChecked has been the steady performer in U.S. at-home testing for half a decade now. The product is a thoughtful catalog of single- and multi-concern panels — thyroid, iron, vitamin D, female hormone, cortisol, omega-3 — each priced as a one-off, each shipped with the same finger-prick collection kit. There is no subscription required; you order what you want, when you want it.

What we like: the targeted-panel format is the easiest entry into the category. If you want a thyroid check and only a thyroid check, you can have it in your hands the week you order. The nurse follow-up on flagged results is real — a live call within 24 hours for anything outside reference range — and the included consultation is included in the panel price, not an upsell.

What we do not like: finger-prick collection is unforgiving for women with small veins or low pressure. Voided samples happen. The dashboard is also functional rather than beautiful — you get your numbers, a reference range, and a brief explanation, but it does not trend like Function's interface does.

Best for: single-question testing, a reader who wants a one-time iron or thyroid read, and women who have a specific clinical question to answer rather than a comprehensive baseline to build. Speak with a qualified healthcare provider about any flagged result before changing course.

Everlywell is the most accessible at-home test on the market. The vitamin D panel sits around $49 in 2026; the women's-health and food-sensitivity panels stretch toward $249. The interface, the unboxing experience, and the dashboard are visibly designed for a first-time at-home tester — and that matters for adoption in a category that still has a learning curve for most readers.

What we like: price-to-result clarity is the best in the category at the entry tier. A vitamin D, a thyroid, a food sensitivity — the product page tells you exactly what you will receive, and the price is the price. Everlywell ships consistently and processes through CLIA-certified labs.

What we do not like: the included clinical follow-up is thin. A flagged result gets you the option of a $59 telehealth consult, but it is not included by default. For a budget-conscious reader, that adds friction at the exact moment you need help. We would also like more rigorous coverage of certain hormone tests where finger-prick precision matters.

Best for: a first at-home test, a budget-conscious reader, women who want a single marker checked without overcommitting. Discuss any flagged result with a qualified healthcare provider.

Modern Fertility — now part of Ro — built the only at-home fertility hormone panel that takes cycle timing seriously. The test must be collected on cycle day three (with allowances for irregular cycles), and the seven markers it covers (AMH, FSH, LH, estradiol, prolactin, TSH, free T4) are the ones a reproductive endocrinologist would order. The app pairs results with context that is actually useful for fertility planning.

What we like: cycle-timing rigor is the single most important thing a hormone panel can get right, and Modern Fertility is the only major at-home brand that treats it as non-negotiable. The app's plain-English explanations of AMH, FSH:LH ratio, and prolactin are written by people who understand the population using them.

What we do not like: the panel is narrow by design. It will not tell you about iron, vitamin D, or general metabolic health. And the app's connection to Ro's fertility services can feel like a soft funnel rather than neutral information.

Best for: women planning a pregnancy in the next one to three years, anyone considering egg freezing, and readers with irregular cycles trying to understand their hormone baseline. Worth discussing the result with a reproductive endocrinologist before any clinical action.

InsideTracker is the original performance-and-optimization testing platform. The product is closer to a wellness operating system than a panel — venous draws at Quest, an algorithmic interpretation that surfaces "InnerAge" and a personalized action plan, and ongoing add-ons that include sleep, fitness, and nutrition recommendations tied to the markers.

What we like: the algorithmic interpretation is genuinely the most actionable in the category for a reader who wants to do something about the numbers. It is also the only product that comfortably handles trending across multiple draws over time, comparable to Function's dashboard. The Ultimate panel covers 48 markers — fewer than Function but more than the targeted-panel category.

What we do not like: the upsells inside the flow are aggressive. Plans, add-ons, supplements, retesting prompts. The base price is fair; the all-in price for a reader who follows every recommendation can climb fast. The optimization framing also leans toward a particular reader — performance-oriented, often male-coded by the marketing — and the women's-health markers are not as integrated as we would like.

Best for: the performance-oriented reader, women already comfortable with tracking biometrics, anyone who wants a layered interpretation rather than a flat result. Worth running flagged results past a clinician before acting on them.

Quest Health is the direct-to-consumer arm of Quest Diagnostics — the same lab that processes a large share of U.S. physician-ordered blood work. The product is what it sounds like: you order a panel online, walk into a Quest draw station, have blood drawn by a phlebotomist, and get the result back as a PDF in one to three business days. No physician referral required.

What we like: the price is shockingly good compared to the at-home category. A ferritin runs about $29; a comprehensive women's panel about $199. The accuracy is, by definition, the same as if your doctor had ordered the same panel — same lab, same equipment, same reference ranges.

What we do not like: no clinical layer. You receive the PDF and that is the product. There is no MD review, no nurse follow-up, no dashboard interpretation. For a reader who knows exactly which marker to test and why, that is fine. For a first-time tester staring at a flagged ferritin and not sure what to do next, the at-home category with clinical follow-up is the better starting point.

Best for: cost-conscious readers, women who already know which marker they want tested, anyone who lives near a Quest draw station. Discuss the result with a qualified healthcare provider, especially if you do not have a clinical interpretation included.
