Don't Read at 45 Minutes! – Why Strict Timing Turns Faint Lines into Clear Results
Steven Walker's experience highlights a common user error: "I left a test on the counter and came back 45 minutes later. The lines had faded badly. Second test read exactly at 10 minutes was perfect. Follow the timing window strictly."
The PawsXfun Horse Pregnancy Test Kit provides a 5-15 minute reading window. Like many immunochromatographic assays, the test lines can fade or change appearance after the recommended reading time.
Why timing matters:
-
Lines can fade – as the sample dries, color intensity may decrease
-
Lines can develop after the window – reading too late may show false results
-
Invalid tests – if the control line fades, the result is invalid
Best practices for accurate reading:
-
Set a timer – don't rely on memory; use a phone or kitchen timer.
-
Read within 5-15 minutes – this is the validated reading window.
-
Read in good light – barn lighting is fine (Carol Young noted "clear purple bands even in poor barn lighting"), but consistent light helps.
-
If you miss the window, retest – don't trust a late reading; use another strip.
Nancy Clark also reported two false negatives from one kit, which could be related to manufacturing issues or timing errors. Her advice to retest with new strips is sound practice for any unexpected result. This kit provides 5 tests, allowing for retesting and confirmation.
