Understanding TPHA

FAQs
Does TPHA indicate active infection? Not always, as TPHA detects lifelong antibodies from past exposure rather than current bacterial activity, so additional tests like VDRL titers or dark-field microscopy are needed to distinguish active from resolved syphilis.
Can it become negative after treatment? No, TPHA typically remains positive for life after infection, even with successful antibiotic treatment, making it a reliable marker of lifetime exposure but not a gauge of cure.
Is fasting required? No, fasting is not required for the TPHA test, as it measures specific antibodies unaffected by recent food intake, allowing for convenient scheduling anytime.
Is it used alone? No, TPHA is not used alone but as a confirmatory test following initial screening like VDRL or RPR to verify true positives and avoid false alarms from non-specific reactions.
Is it reliable? Yes, TPHA is highly reliable with excellent specificity for detecting Treponema pallidum antibodies, making it a gold standard confirmatory test in syphilis diagnosis worldwide.
Who should take this test
The TPHA test confirms syphilis after a screening test such as RPR. It is advised if:
- Your RPR screening test was positive
- You have painless sores, rash or swollen glands
