Anti-DNase B Streptococcal Antibody
Evidence of a recent or past strep infection, especially useful after skin infections.
Consider this test if:
- Joint pain, carditis, or other symptoms suggesting rheumatic fever after a sore throat
- Blood in the urine, swelling, or kidney inflammation following a recent strep infection
- A recent streptococcal skin infection where the ASO titer came back normal
- Pairing it with an ASO titer to widen the window for detecting past strep exposure
- HSA/FSA eligible
- Typical results in 3-5 days · Reviewed by a real clinician
- Drawn at a CLIA/CAP-accredited lab near you ·
Pre-test considerations
No fasting required and no special timing within the day. Because antibodies rise and fall over weeks, a single value is hard to interpret; a repeat sample 2 to 4 weeks later to show a changing titer is often more informative than one reading.

What members say on Trustpilot
What this test is for
Anti-DNase B is an antibody the immune system makes against DNase B, an enzyme produced by group A streptococcus bacteria. A rising or elevated titer is evidence of a recent or past strep infection and is used mainly to support a diagnosis of post-streptococcal complications such as rheumatic fever and acute glomerulonephritis (kidney inflammation). It is the better marker after streptococcal skin infections, where the more common antistreptolysin O (ASO) titer often fails to rise, while anti-DNase B reliably climbs. The antibody appears later than ASO but ultimately turns up in a higher percentage of patients, so the two are frequently checked together when the timing is uncertain. This test confirms prior exposure; it does not detect an active throat infection, which is what a throat culture or rapid strep test is for.

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.
