LERA Beta Launching April 2026 — Join Early Access

Testing 101

How to nail your tests so we can nail your plan.

We test for what matters

When it comes to data, more isn't always better. We focus on the 60+ biomarkers that answer questions, unlock patterns and eliminate any guesswork before we design your personalized plan. You'll complete three tests — each one tells a different part of your story.

Blood

Your metabolic & nutrient blueprint

Finding a convenient Labcorp location is typically easy. However, this a fasting test and it can sometimes take weeks to get an early morning appointment. So, we strongly recommend booking this ASAP. Helpful notes:

If fasting is difficult, schedule early morning.
Stay hydrated and follow all prep instructions.
You’ll need to present your lab order (or lab form) which is available in your LERA app on the “Assess & Test” screen.
Optional: GetLabs is an at-home draw, available in certain markets for an additional fee. Additional tips for GetLabs here.

Stool

The gut deep dive

We know — you’re probably not looking forward to this one. But because the stool test has the longest processing time, we recommend knocking this out early. Important notes:

Do NOT test while on antibiotics (wait until finished).
Discontinue probiotics two weeks prior if possible.
Follow dietary/prep instructions as best you can.
Ship ASAP after collection.
Refrigerate if not shipping immediately.

Saliva

Your hormone & stress response map

Timing is everything with this test. This must be completed during a very specific window of your cycle. We handle the tricky part and figure out the right dates for you to test based on the information you provide in your health assessment. If you follow your testing calendar in the app, you’re good to go. If you miss your testing dates, don’t stress - and definitely don’t test! Just let us know by tapping “Edit my calendar” in the app, and we’ll figure out new testing dates for you. Important notes:

To get a full picture of your hormone health, we test saliva at four different points in the day rather than just once.
All samples must be collected on the same day. Be sure to skip any adrenal support supplements on testing day.
First collection must be within 30 minutes of waking and before you have any caffeine. Ideally, you should refrain from caffeine all day — just do your best.
Freeze samples immediately after collection.

After testing, what comes next

Toxic load quiz

You’ll find the toxic load quiz in your LERA app. On top of uncovering some big insights about your lifestyle and environment, this quiz helps contextualize your lab results. While it’s optional, it’s strongly recommended.

The Reset

This 5-day guided program is the perfect way to prime your body while you await your test results and personalized plan. Designed to gently reduce inflammation and support detox pathways, you’ll feel lighter, clearer and more energetic going into your LERA journey.

Your results & plan

Once you complete your tests and return your samples, it shouldn’t be more than 10 days before you receive your results and plan. When you do, there’ll be all kinds of support and resources available to you. Check them out and customize your experience to suit your preferences and needs.
