Direct Answer
This rapid test detects Fetal fibronectin in Vaginal secretion to support Preterm birth risk. It is a colloidal-gold screening test — a reactive result is presumptive and should be confirmed per the intended use.
Intended Use
Detection of fetal fibronectin (fFN) in cervicovaginal secretion for preterm birth risk.
Clinical Context
fFN is used to stratify preterm delivery risk in symptomatic pregnant women.
Test Principle
Colloidal-gold immunochromatography (lateral flow). The device captures the target analyte (antigen or antibody) on a membrane via labeled antibodies, producing a visible test line within minutes. Qualitative or semi-quantitative, intended as a screening/triage aid — not a replacement for confirmatory laboratory testing.
Limitations
Risk-stratification aid, not diagnostic; interpret with gestational age and clinical findings.
Procurement
Specimen: vaginal secretion. Format: device / strip. CE-marked line.
Interpretation
| Result | Lines | Meaning |
|---|---|---|
| Positive | Test + control line | Target detected (presumptive positive) |
| Negative | Control line only | Below cut-off / not detected |
| Invalid | No control line | Repeat with a new device |
