Patient's question:
Hello:The David brand pregnancy test strips available on the market claim to detect pregnancy as early as 3 days after conception.
I want to ask if this is accurate and what the accuracy rate is?
First follow-up question: Is the test result reliable? Are such test strips really available? Are they precise?
I am very eager to know!
Urgent! Urgent! Urgent!!!!
Doctor's answer:
Early pregnancy test strips are still very accurate. The reasons for inaccuracy are insufficient pregnancy duration and incorrect methods. If your period hasn't arrived when it should, and it's been more than 7-10 days, you should consider pregnancy. It's recommended to do an early pregnancy test. Generally, early pregnancy test strips can detect pregnancy only after the period has been delayed by more than 7-10 days, not based on the time of intercourse. Clinically, pregnancy is usually calculated from the first day of the last menstrual period. If the test shows 2 red lines, it indicates a positive result, suggesting the possibility of pregnancy. Of course, the best time for an early pregnancy test is in the morning. However, 7 days after intercourse, you can also go to the hospital for a blood hCG test. This is the earliest and fastest method. If the test is negative or inconclusive, it may still be pregnancy, but it's too early to detect it yet. You'll need to retest after another 7 days.
