1.2. There are two lines on the pregnancy test stick, namely the control line and the testing line, both showing color, and the testing line is clearly clear: indicating pregnancy.

What are the factors that affect the accuracy of pregnancy test bars?

2.1. Pay attention to the production date on the packaging box, and do not use expired early pregnancy test strips. Due to prolonged use or improper storage of chemicals, they may become invalid.

2.2. Before self inspection, carefully read the instruction manual and then follow the instructions carefully.

2.3. Pregnancy test rods are generally accurate after 7 days of age delay.

2.4. If the pregnancy has just begun or there is a possibility of Ectopic pregnancy, the samples with a low level of HCG detection in the body need to stand for more than 3 minutes. You must carefully determine whether there is a weak positive, and the color band in the detection area only appears faintly.

The best time for a pregnancy test is usually in the morning. The highest HCG value in morning urine is aligned, and if self checking is performed at night, it will more or less affect accuracy.

3.2. Wear disposable plastic film gloves in the box, hold one end of the handle of the pregnancy test stick with your thumb, and tilt the end of the urine suction hole downwards. When observing the pregnancy test stick, pay attention to the downward direction, with the plum blossom pattern facing upwards.

3.3. Align the urine suction hole on the side of the pregnancy test rod to urinate, pass the urine through the suction hole, and maintain the urine collection time for 1-2 seconds.

3.4. Then flip the pregnancy test rod, with the observation window facing upwards, and continue to hold the pregnancy test rod diagonally. When you see purple liquid crawling through the observation window, purple lines will appear in the observation window within 1 minute. After 1 minute, the pregnancy result can be determined, and the result of non pregnancy must be determined after 3 minutes. The consequences of 5 minutes are invalid.
