How to improve the accuracy of early pregnancy test strips
The detection of early pregnancy test strips has the advantages of fast, convenient, sensitivity, so it has also become the preferred method for many women to test whether they are pregnant, but if it is not used properly, the test results of early pregnancy test strips are not very accurate, so how to improve how to improveWhat about the accuracy of early pregnancy test strips? How to improve the accuracy of early pregnancy test strips? Today I will introduce to you how to improve the accuracy of early pregnancy test strips:
1. Pay attention to the production date on the box, and do not use expired early pregnancy test strips.If the test strip is stored for too long (more than 1 year), improper preservation, refrigeration or the tip of the test strip may fail, and the test results will be false negative.
2. Carefully read the manual before doing self -test, and then follow the instructions carefully.Many early pregnancy test strips have detailed explanations. If you read the details of these descriptions several times, think about it repeatedly, generally there will be no problems.However, if you are afraid of pregnancy, you are nervous and panic or look forward to pregnancy, and you may not be able to take pictures and patiently to explain to it, the error is inevitable.
3. Morning is the best time for testing one day.Generally speaking, the most accurate results will be measured with the first excreted urine from early early.Early pregnancy self -test at night will be more or less affected.Because the early urine is concentrated, there is generally the highest HCG level.
4. The speed and quantity of pregnant womens emissions of HCG hormones vary from person to person, so the urine test prematurely does the yin. The reaction may be wrong.Theoretically, it can be measured whether pregnancy can be measured 2 days before the menstrual period, but most women do early pregnancy self -test after missing the normal menstrual period L to 2 days, and often the results are still negative.If you still have menstruation in the future after a week, you should do a self -test again.
5. For example, if the pregnancy is started, or there are ectopic pregnancy such as ectopic pregnancy, the detected urine needs to be static for more than 3 minutes (generally only 1 minute), and carefully distinguish whether it is weak, that is, the color of the detection area is shallow in the control.The color of the area, or only faintly appears.
6. Pay attention to self -test positive results caused by non -pregnancy factors, such as blood, endometrial hyperplasia, ovarian tumors, recent pregnancy, expiration or incomplete abortion, etc.
Early pregnancy test strips cannot be completely accurately determined whether they are pregnant. They can only be used as preliminary testing. They must not be used as the final test results. It is best to go to the hospital for examination to determine whether pregnancy is the most reliable and assured.
Is the early pregnancy test paper accurate?
Many female friends in life are worried that early pregnancy test strips cannot be accurately detected whether they are pregnant, so is the early pregnancy test paper accurate?
If you do your self -test at home, there is no external guidance, and the general test results can only reach 50%to 90%.If you do pregnancy test under the guidance of a doctor, women can use the test strip correctly according to the instructions, and the accuracy rate may be close to 100%.
In general, there are several reasons that will affect the accuracy of the test paper:
1. Detection time.HCG usually appears in the urine after a few days of fertilized eggs, and it can only be detected to reach a certain amount.Therefore, women with normal menstruation need to detect HCG in urine after menstruation delayed.Women with long menstrual cycle or abnormal ovulation need to be detected when menopause is 40-44 days.
2. Dilute urine.If you drink too much water, dilute the urine may cause false negative results.
3. Tests in the morning and evening may have a certain impact on the results.There are generally the highest HCG value in the morning urine, so many instructions are recommended to detect in the morning, but this is not absolute.
4. Pay attention to the length of urine immersion in the test strip during testing.Sometimes the length of the test strip without test strip is too long and the test results may make it difficult to judge.
5. Do not judge whether you are pregnant with test results in the recent pregnancy.Because the HCG can continue positive for a long time after the end of pregnancy (after childbirth, natural abortion and artificial abortion), HCG can continue to be positive.
6. Some diseases and drugs may cause false positive results.Some tumor cells such as hydatidal, velvet cancer, bronchial cancer, and kidney cancer can also secrete HCG.
7. Dont use expired test strips.Because chemical reagents will lose their effect after a long time, pay attention to the production date when buying.
8. Dont use the tide test strip.
9. To get the correct result, it is best to do early pregnancy test strip test in two weeks of menstruation.If the test results are negative, the menstruation is still in the future after 1 week, and it should be done again.The test results are inaccurate in recent pregnancy, because HCG can continue to be positive for a long time after the end of pregnancy (after childbirth, after childbirth, and abortion).Some diseases and drugs may cause false positive test results, such as blood in the urine, or taking some fertility.Some tumor cells such as hydatidal, fleece, bronchial cancer, and kidney cancer can also promote HCG in the body.
