One deep and one shallow, but it's my period

The fact that one dark and one light color on the pregnancy test stick is a symptom of pregnancy may be due to the secretion of female hormones, which will result in a false positive test result. However, when a woman has her period, it is not a symptom of pregnancy, so the pregnancy test stick is a case of false conception. We need to go to the hospital to check the cause of the disease and check the level of hcg hormone in the body to determine whether conception is successful.

The pregnancy test stick is dark and light, but my period has come

Generally speaking, this situation is rare, but it may also be due to the drastic changes in hormone levels before menstruation, which may affect the test results of the pregnancy test stick, resulting in one dark and one light line. However, in this case, the light red line is very inconspicuous and may not be seen without careful observation. Therefore, if one is deep and the other is shallow, you still need to go to the hospital for a thorough examination.

Pregnancy Test Kit Testing Principle: Pregnancy test kit is a kind of in vitro diagnostic (IVD) product. The so-called test is to use the pregnancy test kit to detect human chorionic gonadotropin (HCG) in urine. HCG is a troponin secreted by the placenta of pregnant women. It is distributed throughout the body with the blood, thereby acting on target organs. A certain concentration of HCG is also present in the urine. Currently, most pregnancy test products on the market use the colloidal gold method, which conducts qualitative or semi-quantitative detection of HCG in urine based on the double antibody sandwich principle to determine whether a woman is pregnant. It is worth noting that such pregnancy test products are not 100% accurate, and certain diseases may also cause increased HCG concentrations in the body, resulting in false positive results.

Detect pregnancy earlier: This product has high sensitivity, that is, it can be detected two days after the fertilized egg implants in the uterus, which is equivalent to about 7 days before the next menstruation.

Higher accuracy: This product has a high accuracy rate. Due to the use of multi-layer super-sealed aluminum foil film packaging, it is guaranteed that the product is not easily affected by moisture for a long time. Even the product has a good quality level after being stored for 2 to 3 years.

How to use pregnancy test stick

1. When using, tear open the aluminum foil bag along the notch and take out the pregnancy test stick; [1]

2. Put on the disposable plastic film gloves included in the box, hold one end of the handle of the pregnancy test stick tightly with your thumb, and tilt the end of the urine suction hole downward. Note that the observation side of the pregnancy test stick should face downward, and the plum blossom pattern direction should face upward;

3. Aim at the urine-absorbing hole on the side of the pregnancy test stick and urinate, allowing the urine to pass through the urine-absorbing hole, and maintain the urine collection time for 1 to 2 seconds (please note that urine should not wet the observation window when collecting urine! Otherwise, the pregnancy test stick will become invalid);

4. Then turn the pregnancy test stick over so that the observation window is facing upwards, and continue to hold the pregnancy test stick at an angle. When you see purple-red liquid crawling across the observation window, purple-red lines will appear on the observation window within 1 minute. The pregnancy result can be read after 1 minute, and the non-pregnancy result must be confirmed after 3 minutes. The results read after 5 minutes are invalid! Urine samples collected at any time are suitable for pregnancy test kits. If you are in early pregnancy, morning urine is best.

Faster response: The product can display results within 1 minute, and as fast as 30 seconds. You don’t have to wait for a long time and can find out whether you are pregnant faster.
