Is the second urine sample in the morning accurate for pregnancy testing?
The accuracy of using morning's second urine to test for pregnancy depends on the duration of pregnancy. If menstruation has been delayed for more than 7 days, the results will be accurate regardless of whether it is morning urine or the second urine. The most convenient and economical method for women to test for pregnancy is the pregnancy test strip. If you doubt the result, it is recommended to go to the hospital for blood test for hCG or B-ultrasound examination.
1. Accuracy of Morning's Second Urine Test for Pregnancy
If menstruation has been delayed for more than a week, urine from any time can be used for the test, not necessarily morning urine. If you have just become pregnant and it is not yet time for menstruation, generally, the first urine in the morning is more accurate.
2. Usage of Pregnancy Test Strip
The pregnancy test strip is divided into a test area and an observation area. When dipping the strip in urine, the urine level should not exceed the observation area, which is the position of the first red line. As the urine is absorbed, the first red line appears. If the urine continues to rise and is absorbed, and a second red line appears, it indicates pregnancy. If it is not obvious, it may be a short period of weak positive. No second red line indicates a negative result.
3. Reading Time of Pregnancy Test Strip
Generally, it is correct to read the data within five minutes. If placed for a long time, there may be errors. If the result is negative, you can recheck after two days.
