Erythropoietin (EPO)
The hormone that drives red blood cell production, useful for working out why a blood count is high or low.
Consider this test if:
- A high hemoglobin or hematocrit needs explaining (distinguishing polycythemia vera from a secondary cause)
- Investigating unexplained anemia alongside other blood and iron markers
- Chronic lung disease, sleep apnea, or living at altitude with a persistently elevated red cell count
- Evaluating whether a kidney or other tumor may be driving abnormal EPO secretion
- HSA/FSA eligible
- Results delivered to your dashboard · Reviewed by a real clinician
- Drawn at a CLIA/CAP-accredited lab near you ·
Pre-test considerations
No fasting required. EPO rises with low oxygen, so recent altitude exposure, smoking, and significant blood loss can raise it; results are best interpreted alongside a current hemoglobin and hematocrit.

What this test is for
Erythropoietin (EPO) is a hormone made mainly by the kidneys in response to low oxygen, and it signals the bone marrow to produce red blood cells. It is most useful for sorting out the cause of an abnormal red cell count rather than for routine screening. High EPO is typical when the body is starved of oxygen (chronic lung disease, high-affinity hemoglobins, kidney hypoxia) and in hemolytic anemia, but it can also reflect inappropriate secretion from certain kidney or other tumors. Low or normal-but-inappropriate EPO points toward polycythemia vera when red cell mass is high, since that condition produces extra red cells independently of the hormone. The number is read against your hemoglobin and hematocrit: the same EPO level means very different things in someone anemic versus someone with a high count.

Frequently asked questions
View all FAQsHow does pricing work?
Every test shows the member price next to the standard non-member price, so you can see what membership saves you. The member price is our cost, covering the lab and what it takes to run the service. It is never a profit on the test itself. Mito makes its money on the $9 membership, not on marking up your tests. Membership is $9 per month, and any applicable lab order or draw fee is itemized before you pay.
Where do I get tested?
Choose an available partner lab at checkout. If your cart contains multiple blood tests, Mito helps consolidate the eligible tests at one lab when possible. At-home kits and scans follow the collection or appointment process shown on their product page.
Is this eligible for HSA/FSA?
Yes. Eligible tests can be paid for with an HSA or FSA card at checkout.
When will I get my results?
Your results appear in your Mito dashboard after the laboratory completes processing. A clinician then reviews them before your analysis and personalized action plan are finalized. Timing varies by test, and specialty assays and at-home kits may take longer.
Do I need a physician's order?
No. Mito provides the laboratory order when one is required, so you do not need to arrange a separate physician visit before purchasing.
