What Does a Faint Line Mean on a Pregnancy Test?
On a pregnancy test, a faint test line – or color band – is usually indicative of a positive result, as long as it’s read within the time frame – or reaction time of the test (usually at 5-10 minutes). If you perform the pregnancy test properly and read results within the recommended time frame, then a faint or weak color band in the test area is very likely a positive pregnancy test. Evaporation Lines Evaporation lines, however, can confound results if tests are not interpreted within the clinically recommended time frame. An evaporation line develops when the urine on the test area begins to dry, leaving a faint, usually colorless line. Evaporation lines appear to show up (or not show up) as a result of the composition of the particular urine specimen – and they may appear on any test regardless of brand. Explanations for Faint Positives Testing Too Early: If you test too soon, hCG may not be at a sufficient level for test detection. See the section above on determining when to take
