Early pregnancy test strip detection

Early pregnancy test strip test is a test for women to check whether they are pregnant. It is a kind of preliminary screening test, which has the advantages of fast, convenient, sensitive and high specificity. Generally 40 days of menopause (about 35 days of the earliest), can be measured in pregnant women serum or urine chorionic gonadotropin (HCG) to help diagnose early pregnancy. If you are testing your own early pregnancy test paper, it is best to take the middle section of the first urine in the morning, so that the accuracy is higher. In fact, although the early pregnancy test paper claims to have 99% accuracy, you must not be too convinced of your self-test results. Basic Information Specialist classification: maternity check check classification: urine / kidney function test Applicable gender: whether women are fasting: not fasting Analysis results: Below normal: Normal value: no Above normal: negative: Not pregnant. Positive: pregnancy. Tips: Pay attention to the length of the urine immersion test paper during the test. Sometimes the length of the urine immersion test strip is too long, which may make the test results difficult to judge. Expired test strips will lose their usefulness due to long chemical reagents, and the wet test strips will also fail. Normal value A red line (negative) in the early pregnancy test strip showed only a purple-red band in the quality control area (C), and no purple-red band appeared in the test area (T), indicating that it was not pregnant. Clinical significance Abnormal results have false positives or false negatives. Two red lines (positive) in the early pregnancy test strip are located in the test area (T) and the other in the quality control area (C), indicating that they are pregnant. There is no red line (invalid) in the early pregnancy test strip (C). There is no purple-red band in the control area (C), indicating that the incorrect operation process or the reagent strip has deteriorated. Some diseases and drugs may cause false positive results. Some tumor cells such as hydatidiform mole, choriocarcinoma, bronchial carcinoma and kidney cancer can also secrete HCG. People who need to be examined: women who have delayed menstruation and suspected of having been pregnant. Positive results may be diseases: precautions for ectopic pregnancy Taboo before inspection: 1. Time of detection. HCG is usually detected in the urine after menstruation is delayed in women, and women with long menstrual cycles or abnormal ovulations may be detected 40 to 44 days after menopause. 2. Urine dilution. If the water is too much, diluting the urine may result in a false negative result. 3. Experimenting in the morning and evening may have an effect on the results. There is generally the highest HCG value in the morning urine. Requirements for inspection: Pay attention to the length of the urine immersion test paper during the test. Sometimes the length of the urine immersion test strip is too long, which may make the test results difficult to judge. Expired test strips will lose their usefulness due to long chemical reagents, and the wet test strips will also fail. Inspection process 1. Read the instruction manual thoroughly before performing the test. Return the reagent and urine sample to room temperature (20 °C - 30 °C) before use. 2. Remove the reagent strip from the original packaging aluminum foil bag and use it as soon as possible within 1 hour. 3. Insert the reagent strip into the urine specimen in the direction of the arrow. Note: The urine level should not exceed the marking line of the reagent strip. 4. After at least 5 seconds, remove and lay flat on a clean and flat surface to observe the results. 5, waiting for the appearance of the purple band, the test results should be read in 3 minutes. After 10 minutes, the judgment was invalid. Not suitable for the crowd There are no special taboos. Adverse reactions and risks No related complications or hazards.
