Human pregnancy test

Principles of Human pregnancy test

Detecting the concentration of HCG in the urine to determine whether a woman is pregnant is a reliable indicator to assist clinical judgment of pregnancy. HCG, or Human Chorionic Gonadotropin, is a glycoprotein produced by the placenta of pregnant women during pregnancy and can be excreted from the urine through the glomeruli.

Causes of human pregnancy test misdetection

  1. The detection time. HCG usually appears in the urine a few days after the fertilized egg is implanted, and it must be detected in a certain amount. Therefore, for women with normal menstruation, HCG may be detected in the urine after menstruation is delayed. And women with long menstrual cycles or abnormal ovulation can only be detected after menopause for 40-44 days.
  2. Urine dilution. If you drink too much water and dilute your urine, you may cause false negative results.
  3. Experiments in the morning and evening may have a certain effect on the results. The urine in the morning usually has the highest HCG value, so many instructions recommend testing in the morning, but this is not absolute.
  4. Pay attention to the length of urine immersion test paper during the test. Sometimes the length of the urine immersion test strip is too long, which may make the test result difficult to judge.
  5. Don't judge whether you are pregnant based on the test results in the case of recent pregnancy. HCG can continue to be positive for a long period of time after termination of pregnancy (after childbirth, spontaneous abortion and artificial abortion).
  6. 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.
  7. Do not use expired test paper. Because the chemical reagent will lose its effectiveness after a long time, so pay attention to the date of production when buying.
  8. Do not use test strips that have been damp.

Principles of Pig pregnancy test

Take Pig Pregnancy Rapid Test as an example, the body's endocrine changes after pregnancy, of which progesterone (P4) is the most obvious change. Progesterone is a steroid hormone secreted by the corpus luteum and placenta. The performance of a sexual cycle rises daily from low to peak at 15 days After the decline, it fell to the lowest level of 0 ng / ml in about 19 days, maintained for about 1 day, and then gradually increased. Progesterone continues to maintain a high level after the pig is conceived. The urine progesterone reaches 0.05 μg / ml in 26 to 30 days. This product uses progesterone as the detection target and judges whether it is pregnant by the dose of progesterone.

Pig pregnancy test usage

  2. Suck the urine with the straw, and drop 3 to 4 drops in the circular sample hole (S) of the test board.

  • Negative: Only one color band appears in the control area (C), indicating that the tested pig is not yet pregnant and can be re-matched.
  • Invalid: No ribbon appears in the control area (C), indicating that the test failed or the test board is invalid, please take another test board and re-test. Follow the instructions in the manual.
