At home blood test for women: hormones, thyroid, iron and heart markers by life stage

Quick answer

The right at home blood test for women depends on why you are testing. For cycle or fertility questions you need hormones taken on the right cycle day (FSH, LH and estradiol on day 3; progesterone about 7 days before your period). For fatigue, hair loss or heavy periods, thyroid and ferritin matter more. From your 40s, add heart and blood sugar markers. SiPhox covers most of this across three panels included in one membership at $124 plus $25 shipping per test: Longevity Essentials (estradiol, FSH, LH, ferritin, vitamin D, ApoB, HbA1c), Hormone Focus (adds progesterone, testosterone and prolactin) and Thyroid Focus (TSH, free T4, free T3 and two antibodies). It does not test AMH.

What to test by life stage

Symptoms like these have many causes. Use results to have a better conversation with your doctor, not to self-diagnose.

Cycle-day timing

Reproductive hormones swing through the month, so the day you test changes what the number means. Day 1 is the first day of your period.

• FSH, LH and estradiol: day 3 for basic fertility testing, according to Cleveland Clinic.
• Progesterone: day 21 of a 28-day cycle, or about 7 days before your next period, to check whether you ovulated. With longer or irregular cycles, count back from your expected period.
• Testosterone and cortisol: in the morning, at the same time each test.
• Hormonal contraception changes these hormones, so ask your clinician whether testing makes sense while you are on it.

The chart is why cycle day matters: an FSH of 10 IU/L is ordinary in the follicular phase but above ARUP's luteal range, and after menopause the whole range sits several times higher. FSH also swings from month to month in perimenopause, which is why doctors lean on symptoms and cycle history.

MedlinePlus notes that FSH testing usually is not needed to confirm menopause at 45 or older, because high FSH is expected then; it is more useful when symptoms start before 45 or the cause is unclear. Our at-home hormone test for women covers kit choice in more detail.

Thyroid

Thyroid symptoms (tiredness, weight change, hair thinning, cycle changes) overlap with many other things. A TSH alone is the usual screen. A fuller picture adds free T4, free T3 and TPO antibodies, which point to autoimmune thyroid disease. SiPhox includes TSH on Longevity Essentials and the full set, plus thyroglobulin antibodies, ferritin and cortisol, on Thyroid Focus (21 markers). For comparison, Labcorp OnDemand's TSH and free T4 test is $89 for two markers at a lab, while Thyroid Focus is $149 for 21 at home. If you already take thyroid medication, ask your prescriber how long after a dose change to retest. See our at-home thyroid test guide.

Ferritin and iron

Ferritin reflects your iron stores. MedlinePlus lists heavy menstrual bleeding and pregnancy among the reasons to check iron before symptoms appear. Ferritin is on SiPhox Longevity Essentials and Thyroid Focus; a full iron panel (iron, TIBC, UIBC, iron saturation) is only on Ultimate 360 and GLP Optimization. Ferritin also rises with inflammation, so a normal ferritin during an illness can hide low stores. More in our at-home iron test guide.

Vitamin D

The NIH Office of Dietary Supplements uses these serum 25(OH)D levels: below 12 ng/mL (30 nmol/L) is associated with deficiency, 12 to 20 ng/mL (30 to 50 nmol/L) may be inadequate for some people, 20 ng/mL (50 nmol/L) or more is adequate for most, and above 50 ng/mL (125 nmol/L) may cause harm. Labs use different cut-offs, so check the range on your report. Vitamin D is on Longevity Essentials and Ultimate 360.

Heart and metabolic markers

Heart risk in women is often checked late. The 2018 AHA/ACC cholesterol guideline lists premature menopause (before 40) and pregnancy conditions such as preeclampsia among the risk enhancers doctors should consider, alongside ApoB of 130 mg/dL or more and Lp(a) of 50 mg/dL (125 nmol/L) or more. Longevity Essentials includes ApoB, Lp(a), the lipid panel, hs-CRP and HbA1c by default.

Which SiPhox panel covers what (women)

Generated from SiPhox's panel lists on September 29, 2026. "Men only" means the panel reports it for men but not for women.

Hormone Focus is the only core panel with progesterone, testosterone for women, prolactin and the free androgen index, which is why it is the one to use for PCOS-type questions. Ultimate 360 ($274 per test) covers everything above except AMH.

PCOS-type questions

If you have irregular periods, acne or excess hair growth, a clinician will usually look at androgens, pituitary hormones and blood sugar. Hormone Focus covers most of the blood side: total testosterone, calculated free testosterone, SHBG, the free androgen index, DHEA-S, LH, FSH and the LH:FSH ratio, and prolactin. Longevity Essentials adds HbA1c, C-peptide and the triglyceride:HDL ratio for the metabolic picture. What is missing is AMH, fasting insulin and glucose. A diagnosis also depends on your cycle history and often an ultrasound, so take the results to your doctor rather than drawing conclusions from them alone.

The honest gaps

• No AMH. Anti-Mullerian hormone estimates egg supply and is used in fertility planning and PCOS workups. MedlinePlus notes it cannot predict whether you will get pregnant naturally. If you need it, order it through your doctor or a lab.
• No fasting insulin or glucose. For insulin resistance, SiPhox offers HbA1c, C-peptide and the triglyceride:HDL ratio instead. See at-home insulin resistance test.
• No CBC by default (+$45 add-on), so no full anemia workup unless you add it.
• B12, folate and iron studies only on Ultimate 360 or GLP Optimization.
• Cycle timing is on you. SiPhox ships a kit on your chosen cadence, so plan the collection day around your cycle when testing hormones.

How to prepare for a women's blood test at home

• Write down your cycle day and whether you use hormonal contraception, and keep the note with your results.
• Collect in the morning if the panel includes testosterone or cortisol, and at the same time on every repeat.
• Wait if you are ill. Infection raises hs-CRP and can raise ferritin, which would hide low iron stores.
• Pregnancy changes many reference ranges. If you are or might be pregnant, talk to your clinician before relying on a home panel.
• Hydrate and warm up before an arm-device draw; our EasyDraw guide covers the steps.

A year of testing for women: plans and costs

Prices include $25 shipping per test. Because kits arrive on your chosen cadence, collect a hormone kit on the right cycle day rather than the day it arrives; check the kit's instructions for how long you can hold it before collecting. All tests can be paid with an HSA or FSA; see HSA eligible blood tests.

Blood test for women over 40

From 40, a sensible at-home set is: FSH and estradiol if cycles are changing, TSH, ferritin, vitamin D, a lipid panel with ApoB, Lp(a) once, HbA1c, and kidney and liver markers every year or two. On SiPhox that is Longevity Essentials twice a year plus Heart & Metabolic and Thyroid Focus once each: four tests for $596 a year. If you would rather do one big panel a year, compare our full body blood test options or SiPhox vs Function Health.

Start with Longevity EssentialsEstradiol, FSH, LH, ferritin, vitamin D, TSH, ApoB and HbA1c in one test. Switch to Hormone or Thyroid Focus next time.
