In daily life, pregnancy test strips are a very common pregnancy test product, it is easy to use, high accuracy, and is deeply liked by people, many female friends will use pregnancy test strips to test pregnancy results. So, how long does it take to test a pregnancy with a test strip? When is the most accurate time to use a pregnancy test strip?
In general, pregnancy test strips are most accurate when used between 7 and 10 days after menstruation, when the urine hormone concentration will be higher and the results will be more accurate. So what is the best time of day to use a pregnancy test strip? Let's take a closer look!
The detection principle of the pregnancy test strip is to detect the concentration of chorionic promoting gonadal hormone in human urine, although this hormone will appear in the urine a few days after pregnancy, but because the concentration is relatively small, it is not easy to detect, and it can only be detected when pregnancy reaches a certain time, and the best time is between 7-10 days after menstruation is delayed, at this time the concentration of human chorionic promoting gonadal hormone in the urine of most women will reach the highest value, and the test results are also the most accurate.
It is best for women to take a pregnancy test when they urinate for the first time after waking up in the morning, because the urine concentration at this time is higher and contains more human chorionic gonadotropin, so if you are really pregnant, the probability of testing positive for early pregnancy will be higher.
Women use pregnancy test strips for pregnancy self-testing, without any external guidance, the general test results can only achieve an accuracy rate of 50% to 90%, but if the pregnancy test is done under the guidance of a doctor, women can use the test strips correctly according to the instructions, and the accuracy rate of the test may be close to 100%.
1. Doing tests in the morning and evening may have a certain impact on the results, and the urine in the morning generally has the highest HCG value, so it is generally recommended that women be tested in the morning.
2. The time of filial piety detection: HCG generally appears in the urine a few days after the implantation of the fertilized egg, and it can only be detected when it reaches a certain amount, so for women with normal menstruation, it is possible to detect HCG in the urine after menstruation is delayed, and women with long menstrual cycles or abnormal ovulation need to be detected when they stop menstruation for 40-44 days.
3. Urine dilution: If you drink too much water before the test, it will also cause the urine to be diluted and lead to false negative results.
4. Pay attention to the length of the urine immersion test strip during the test, if the length of the urine immersion test strip is too long, it may make the test result difficult to judge.
5. Do not judge pregnancy based on the test results when you have recently had a pregnancy, because after the termination of pregnancy, such as after childbirth, spontaneous abortion and artificial abortion, HCG can continue to be positive.
6. Some diseases and drugs may cause false-positive results, and some tumor cells such as molar pregnancy, choriocarcinoma, bronchial cancer and kidney cancer can also secrete HCG.
7. Do not use expired and damp test strips, so as not to lose the effectiveness of the test strips.

1. 1-2 weeks of pregnancy. The working principle of pregnancy self-test using pregnancy test strips is to detect the hcg value, that is, the value of human chorionic gonadotropin, this hormone is made by the placenta, after 10-14 days after conception, the human body begins to secrete chorionic gonadotropin, which will appear in the blood first, and then appear in the urine with the circulatory system, but due to the small amount, it is not easy to test it at first, and it is not increasingly obvious until 1-2 weeks after pregnancy, and the effect is not good if it is too early and too late.
2. Women must read the instructions completely before taking the pregnancy test strip test, restore the reagent and urine sample to room temperature of 20-30 degrees before use, take out the reagent strip from the original packaging aluminum foil bag, and use it as soon as possible within 1 hour, and insert the reagent strip into the urine specimen in the direction of the arrow.
Note: The urine level should not exceed the marker line of the reagent strip, at least 5 seconds later, take it out and lay it flat on a clean and flat table to observe the results, wait for the appearance of the purple-red band, the test results should be read at 3 minutes, and the test results should be judged invalid after 10 minutes.
3. It is best to use morning urine for pregnancy test strips, because the urine from the morning generally has the highest hcg value, and the test results are the most accurate, but if you do a pregnancy self-test at night, the accuracy will be more or less affected.
41. The pregnancy test strip can only detect whether you are pregnant, and cannot judge whether it is a normal pregnancy or an ectopic pregnancy, and the human chorionic gonadotropin (HCG) of an ectopic pregnancy may be lower than that of a normal intrauterine pregnancy, and the test result may be weakly positive.
2. Due to the influence of external factors, such as taking hormone drugs, hormonal contraceptives or some diseases, etc., can lead to false negatives or false positives in the pregnancy test strip test, which affects the results of the test, so the early pregnancy test strip test can only be used as the first step of screening.
3. The pregnancy test strip cannot detect the size and location of the gestational sac, so in order to have a healthy baby, no matter what the test result is, you must cooperate with the doctor to conduct a comprehensive examination.
