When must you take the Home Pregnancy Test?
Many home pregnancy tests device claim to be accurate as early as the first day of the missed period. You might get accurate results if you wait until after the first day of the missed period. This is because shortly after the fertilized egg attaches with the uterine lining, the placenta forms and produces hormone human chorionic gonadotropin (HCG). This hormone enters your bloodstream and urine.
Furthermore, during the early pregnancy period, HCG concentration increases rapidly. The earlier you take the pregnancy test, the harder you will get the result. You need to keep in mind that the timing of the ovulation varies month to month. The fertilized egg implants in the uterus at different times. This also affects the timing of HCG production.

In many cases, there can be 13-day different when ovulation occurs. Pregnancy bleeding, recent hormonal contraceptive use or breastfeeding can all interfere with accurately knowing your dates.

The more of the fragmented hormone around, the more likely the first antibody will capture the fragment instead of the hormone.

The accuracy of the digital pregnancy test depends on the timing. The inaccuracy of the test depends on the improper usage of the product. It is highly advised to use the device early morning when the HCG concentration is highest and follow the package instructions precisely for results to be accurate.
Blood Pregnancy Tests-
