What do you think of pregnancy test paper

Take urine. Pregnancy test paper package will generally have a urine cup, used to hold the urine sample, take out the urine sample.

Put the test paper and urine at the same room temperature. Open the outer package of the test paper and place it at the same room temperature as the urine sample.

Insert the test paper into the urine sample. Insert the bulged end of the test paper into the urine sample. Note that there is a line marked with Max on the test paper. The insertion depth should not exceed the max line, but it should not be too shallow, so as not to affect the detection.

matters needing attention

If the test paper of early pregnancy is stored for a long time (more than 1 year), or the test paper of early pregnancy is affected with damp, and it is not kept at normal room temperature (it should not be cold stored), it may be invalid, and the test result will be false negative. If the pregnancy is just beginning, or ectopic pregnancy (ectopic pregnancy) is possible, the hCG level in the body is generally low, the test sample needs to stand for more than 3 minutes (generally only 1 minute), and it is necessary to carefully identify whether there is weak positive - only faint color bands in the test area. After 3 months of pregnancy, hCG level decreased, and urine test sometimes appeared negative or weak positive.
