Direct Antiglobulin Test (DAT)
Detects antibodies coating your red blood cells, the key test when hemolysis is suspected.
Consider this test if:
- Lab results suggest hemolysis: dropping hemoglobin with high reticulocytes, LDH, and bilirubin
- Investigating fatigue, pallor, dark urine, or jaundice alongside signs of anemia
- Evaluating a suspected transfusion reaction after receiving blood
- Suspected drug-induced or autoimmune hemolytic anemia
- Assessing a newborn for hemolytic disease related to maternal antibodies
- 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 and no special timing. The sample is whole blood collected in an EDTA (pink-top) tube. Tell the ordering clinician about recent transfusions and any medications, since both can affect the result and its interpretation.

What this test is for
The direct antiglobulin test, also called the direct Coombs test, detects immunoglobulin or complement bound to the surface of your red blood cells while they are still in your bloodstream. A positive result points to immune-mediated destruction of red cells, the mechanism behind autoimmune hemolytic anemia, transfusion reactions, hemolytic disease of the newborn, and certain drug-induced hemolytic reactions. It is the standard first step when bloodwork shows hemolysis: a falling hemoglobin, a high reticulocyte count, elevated LDH and bilirubin, and low haptoglobin. A positive DAT confirms the process is antibody-driven, which separates immune causes from non-immune ones and changes how the anemia is worked up and treated. A negative result is informative too, since it steers the search toward non-immune causes of red cell breakdown.

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 — never a profit on the test itself; Mito makes its money on the $9 membership, not on marking up your tests. Membership is $9/mo, and you still pay the lab’s order fee. Prices are itemized before you pay, with no hidden fees.
Where do I get tested?
Choose a partner lab (Quest, Labcorp, or BioReference) at checkout. If your cart spans multiple tests, we consolidate the whole order onto a single lab so you only make one visit.
Is this eligible for HSA/FSA?
Yes. This test is HSA/FSA eligible, and you can pay with your HSA/FSA card at checkout.
When will I get my results?
Your results post to your dashboard once your lab completes them, then a clinician reviews them and your full analysis and personalized action plan (with clear next steps) follow. Turnaround varies by test: specialty assays and at-home kits take longer, and each test shows its expected turnaround before you buy.
Do I need a doctor’s order?
No. Mito provides the lab order for you, so you can book and get tested without a separate doctor visit.
