An at-home estrogen test kit is a mail-in lab test that measures estradiol from a finger-prick blood sample, or a urine kit that tracks estrogen metabolites like E1G.
In the US, an at-home estrogen test kit goes by many brand names and takes more than one form. The most common type mails you a small blood collection kit, and most also ask for a saliva or urine sample. You register the kit online, send the samples to a lab, and get a digital report in about a week. Which kit is right for you comes down to which hormones you want measured, how you want to collect the sample, and what you can spend.
What’s Actually In An At-Home Estrogen Test Kit?
The top kits measure estradiol plus a set of related hormones, and none of them measure “estrogen” as one single number. Estradiol (E2) is the main estrogen measured in blood; urine-based kits often track the metabolite estrone-3-glucuronide (E1G) instead. The difference matters when you compare results between brands.
Current US-market test options measured in recent 2026 reviews:
| Test Kit | Sample Type | What It Measures | Price |
|---|---|---|---|
| Everlywell Women’s Health Test | Finger-prick blood + saliva | Estradiol, progesterone, LH, FSH, DHEA-S, cortisol, TSH, free T3, free T4, free testosterone, thyroid peroxidase antibodies | $249 |
| myLAB Box Hormone Test | Blood + saliva | FSH, estradiol (E2), progesterone | $119 |
| Modern Fertility Hormone Test | Finger-prick blood | AMH, TSH, FSH, E2, free T4, prolactin, LH | $179 |
| GetTested Female Hormone Test | Saliva | Estradiol (E2), progesterone, testosterone, DHEA-S, cortisol | NY-approved option |
The Everlywell Women’s Health Test is the most comprehensive pick, and Healthline’s 2026 review confirms it measures estradiol, progesterone, LH, and FSH. One caveat: Everlywell’s product page describes the panel as 10 key biomarkers, while its published test list enumerates more analytes, so check the current on-page wording before you order.

How Home Estrogen Tests Work
Most kits use finger-prick blood. You prick a fingertip, fill a small tube, and mail the sample to a lab in the prepaid envelope. Saliva-based kits like GetTested skip the prick entirely and may be the better fit if you’re needle-averse.
Registration is done on the brand’s website or in its app by scanning the QR code on the box. That step links your sample to your results, so do it before you collect anything. Results come back digitally — typically in 5 to 7 days for Everlywell, per Medical News Today, or 2 to 5 days per Healthline. Some kits include a physician review in the price, which the Amazon listing for Everlywell explicitly notes.
One more thing to check before ordering: availability. Some kits are restricted by state or region. GetTested’s US product page states it’s NY-approved, while some Amazon-listed kits note they are not available in New York or Rhode Island.
Tips For Using A Home Estrogen Test Kit
To get a usable result, collect samples first thing in the morning unless the kit says otherwise. Follow the kit’s day-of-cycle guidance when it gives one, because estradiol levels fluctuate across the menstrual cycle. Keep everything at room temperature until you mail it, and don’t forget to activate the kit before shipping. When the report arrives, take it to a clinician — at-home tests are tools for insight, not a replacement for lab testing or medical advice.
FAQs
Are at-home estrogen tests as accurate as lab tests?
Most at-home kits are analyzed in the same CLIA-certified labs clinics use, with the finger-prick method slightly less exact than a venous blood draw. Accuracy also depends on the hormone being tested and when you sample during your cycle. Results are reliable for screening and tracking trends, but a doctor should interpret them.
What is the difference between E2 and E1G?
E2 is estradiol, the primary estrogen measured in blood. E1G is a urine metabolite of estrogen, and urine-based kits measure it as a proxy. The two methods are not directly interchangeable, which is why comparing numbers between a blood-based kit and a urine-based kit can be misleading.
Do I need to fast before using these kits?
No, most at-home estrogen tests do not require fasting, though they may ask you to test at a specific time of day. Saliva tests usually require waiting at least 30 minutes after eating, brushing, or using mouthwash. Always follow the kit-specific instructions, since collection rules vary by sample type.
