Chlamydia Testing: DFA test – Is it Reliable?
Chlamydia DFA Testing: What You Need to Know
DFA or direct fluorescent antibody test uses antibodies against the LPS molecule in the bacterial cell wall or the major outer membrane protein (MOMP) of C. trachomatis. Urethral, vaginal and rectal swabs can be tested. Test results take a few days.
The tests are usually performed with a swab.
The DFA test for Chlamydia has high specificity but false-positive results can occur. In general, the test has been supplanted by NAATs (Nuclear acid amplification tests) which are more sensitive and specific. Studies show that a small number of infections can be detected by DFA that are not detected by other methods. Chlamydia DFA test is not as sensitive as NAAT tests and some infections may be missed.
At New York Urology Specialists, we offer FDA-approved MicroTrak® Chlamydia trachomatis Direct Fluorescent Antibody (DFA) testing system.
