Early Pregnancy Test Accuracy: Timing and Detection of hCG
It is possible to miss a period yet still be too early for a pregnancy test to detect the hormone human chorionic gonadotropin (hCG).
Detection Timeline
- The earliest a urine or blood test can detect hCG is typically 10–14 days after ovulation.
- In some individuals, hCG levels take longer to reach detectable thresholds.
Recommendation
If you have missed a period and suspect pregnancy, wait a few days before testing to improve accuracy. Alternatively, consult a healthcare provider for advice and further testing.
