A Lyme test that catches what standard tests miss? New research suggests it may be possible. 🔬
In the first 1–3 weeks of Lyme disease, standard two-tier tests pick up fewer than half of cases. That’s the same window when antibiotics work best.
A new Journal of Clinical Microbiology study describes LymeSeek, a single blood test from Aces Diagnostics that reads 16 antibody signals at once. In people with early Lyme, it detected over 90% of cases within two weeks. It also caught 21 of 30 cases that standard testing missed, including some with no rash.
LymeSeek isn’t available to the public yet. The FDA clearance process has begun, and more studies are under way.
NOTE: For now, LymeSeek targets Borrelia burgdorferi, the main North American Lyme species, using antibodies to a panel of its antigens. It is not a cleared clinical test yet and still needs further validation, including planned clinical trials. It also will not tell a patient whether they have coinfections. It is a promising research tool for the early weeks of illness, when standard two-tier tests often miss cases, though a result in the first few days after a tick bite can still be negative.
