What it measures

Four markers. The whole thyroid story.

A standard TSH alone can’t distinguish a sluggish thyroid from autoimmune thyroiditis from a normal-but-low-converting one. The Thyroid Kit measures all four, so you and your clinician can act on the right answer.

Marker 01

TSHThyroid-Stimulating Hormone

A pituitary hormone that signals your thyroid to work harder. Elevated TSH means your body is asking for more thyroid hormone than it’s getting.

Why it matters: Even subclinical elevation impairs ovulation, implantation, and raises miscarriage risk. Most fertility clinicians target a TSH below 2.5 for anyone trying to conceive.
Optimal for trying0.4 – 2.5 mIU/L
General reference range0.4 – 4.0 mIU/L
Cycle day to testAny day
Marker 02

Free T4Free Thyroxine

The main hormone your thyroid produces and ships out. “Free” means we’re measuring the unbound, biologically active fraction.

Why it matters: A normal TSH with a low Free T4 can indicate central hypothyroidism — a problem with the pituitary, not the thyroid itself. TSH alone misses it.
Reference range0.8 – 1.8 ng/dL
Cycle day to testAny day
Marker 03

Free T3Free Triiodothyronine

The active form of thyroid hormone — what your cells actually use. Your body converts T4 to T3, and that conversion isn’t guaranteed to be efficient.

Why it matters: Some people have normal TSH and Free T4 but poor T4-to-T3 conversion, leaving them functionally hypothyroid despite “normal” results. Free T3 surfaces this.
Reference range2.3 – 4.2 pg/mL
Cycle day to testAny day
Marker 04

TPO AntibodiesThyroid Peroxidase Antibodies

An autoimmune marker. When elevated, your immune system is producing antibodies against your own thyroid — the hallmark of Hashimoto’s thyroiditis.

Why it matters: TPO antibodies independently raise miscarriage risk, even when TSH is in range. Identifying them early lets your clinician adjust monitoring and treatment thresholds.
Negative< 35 IU/mL
Borderline35 – 100 IU/mL
Elevated> 100 IU/mL

Is this kit right for you?

When TSH alone isn’t enough.

The Thyroid Kit is for anyone who suspects their thyroid is part of the picture — and who wants more than the single TSH most physicians order. Useful for men and women.

Already covered in Full Fertility Kit

Heads up

Don’t double up:

  • The Full Fertility Kit ($299) already includes TSH and Free T4
  • The Thyroid Kit pairs best with the Basic Fertility Kit ($199), which only covers TSH
  • If you have a confirmed thyroid condition, this kit is also useful as a stand-alone monitoring panel
  • For men: useful as a stand-alone if you have suspected thyroid involvement in fertility
Often paired with

Layer in the rest.

If you’re using the Thyroid Kit on its own, consider pairing it with the Basic Fertility Kit for ovarian markers, or the Inflammation Kit for implantation readiness.

Basic Fertility Kit

Adds AMH, FSH, LH

$199

The three most predictive markers for conception and egg-freezing decisions. Pairs cleanly with the Thyroid Kit for a more complete first-pass workup.

Inflammation Kit

For everyone trying to conceive

$99

Measures hs-CRP and Vitamin D. Especially relevant if your TPO antibodies come back elevated — autoimmune thyroid disease and chronic inflammation often travel together.

Questions, answered

Before you order.

How accurate are at-home tests compared to going to a clinic?

The same CLIA-certified labs that process physician-ordered bloodwork process Eve samples. The dried blood spot method we use has been clinically validated across all three markers, and results are reviewed by a licensed clinician before being released.

Is this covered by insurance, HSA, or FSA?

Eve kits are HSA/FSA eligible — we accept HSA/FSA cards directly at checkout, and we provide an itemized receipt you can submit for insurance reimbursement. Many plans cover diagnostic testing even when they exclude treatment, so it’s worth asking.

When in my cycle should I test?

TSH and AMH can be tested any day. FSH and LH are most informative on day 2 or 3 of your period. If your cycles are irregular, the app walks you through the right timing for your situation — or flags that day-independent markers are still valuable on their own.

Can I test while on birth control?

You can, but it affects what some markers mean. Hormonal contraception suppresses LH and FSH and mildly affects AMH. If you’re on birth control, the app adjusts your interpretation accordingly — and for the most accurate baseline, we recommend testing 2–3 months after stopping.

What if my results show something concerning?

Every set of results comes with plain-language interpretation, context about what each number means for your goals, and a ranked set of next steps. For flagged markers, we include what to ask your OB/GYN or a reproductive endocrinologist — and the app can help you find a clinic near you.

How is my data protected?

Everything is encrypted, HIPAA-compliant, and stored separately from your personal info. We never sell health data, ever. You can delete your account and all associated data at any time, and we’ll confirm deletion in writing.

What’s your return policy?

Unopened kits can be returned within 30 days for a full refund. Once your sample is in the lab, we can’t refund the kit — but if something goes wrong with the collection or the sample is unusable, we’ll send you a replacement kit for free.
