How to quickly test for pregnancy

The most common way to test pregnancy is to use a pregnancy test stick or pregnancy test paper, but the results obtained by this method sometimes have errors. It is recommended to go to the hospital for confirmation.

Blood hCG test: "Quantitative" blood test of hCG value can respond to pregnancy more sensitively and accurately than the ordinary "qualitative" urine test with early pregnancy test paper, with an accuracy rate of over 99%. In addition, for multiple pregnancies, ectopic pregnancies, abnormal embryonic development retardation, hydatidiform mole, certain endocrine diseases or tumors, etc., the blood hCG value is combined with the clinical situation and other examination results, and a comprehensive analysis can often lead to a correct judgment.

Urine hCG test: Urine hCG pregnancy test method is to determine whether a woman is pregnant by detecting whether there is hCG in her urine. In order to improve accuracy and reduce errors, female friends are best to go to the hospital for blood hCG test.

Ultrasound test: Some women mistakenly believe that they can use ultrasound (B-ultrasound) to check if they are pregnant. In fact, it is necessary to wait until about 5 weeks of pregnancy to see whether there is a blastocyst in the uterus. Ultrasound testing can not only detect the growth of the blastocyst, but also check whether there is a possibility of ectopic pregnancy.

How long does it take to detect pregnancy?

There are many ways to test for early pregnancy, and the test time for different methods is different. Under normal circumstances, you can go to the hospital for a blood hCG test to see if you are pregnant 7-10 days after having sex. You can also use an early pregnancy test strip or pregnancy test stick to test for pregnancy about 3-5 days after the menstrual period. The most reliable method is a B-ultrasound pregnancy test performed in the 5th week of pregnancy and 35 days after pregnancy.

Blood hCG test: You can go to the hospital to do a blood HCG test about 10 days after sex to check the HCG content in the blood. This test is faster and more accurate than a normal urine test. Quantitative blood HCG test can respond to pregnancy more sensitively and accurately than qualitative urine test with early pregnancy test strips, with an accuracy rate of more than 99%.

Early pregnancy test strips: pregnancy can be checked 3-5 days after the menstrual period. hCG usually appears in urine a few days after the fertilized egg implants, and it can only be detected when it reaches a certain amount. Therefore, for women with normal menstruation, HCG can only be detected in urine after the menstruation is delayed. Women with long menstrual cycles or abnormal ovulation can only be detected when the menstruation is amenorrhea for 40-44 days.

B-ultrasound examination: As early as the fifth week of pregnancy, which is one week after the menstrual period, a round halo in the uterus can be shown on the B-ultrasound screen, also known as the pregnancy ring. The dark area inside the ring is amniotic fluid, and the rhythmic fetal heartbeat can also be seen in it. Using B-ultrasound to diagnose early pregnancy is the most accurate and reliable method.

How to use a pregnancy test stick

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

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

Aim at the urine suction hole on the side of the pregnancy test stick and pee, let the urine pass through the urine suction 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);

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, a purple-red line will appear on the observation window within 1 minute. The pregnancy result can be determined after 1 minute, and the non-pregnancy result must be determined after 3 minutes. The result determined after 5 minutes is invalid!

Urine samples at any time are suitable for pregnancy test sticks. If you are in the early stages of pregnancy, morning urine is the best.

How to use pregnancy test strips

1. Collect urine in a clean, dry container (urine at any time is suitable for this test. If you have just become pregnant, the first urine in the morning is best).

2. Hold the pregnancy test paper and dip the end with the arrow mark into the container filled with urine. After about three seconds, take it out and lay it flat. Observe the result within 30 seconds to 5 minutes.

3. Refer to the instructions on the product. If only the control line appears, it means you are not pregnant; if both the control line and the test line are colored, and the color of the test line is obvious and clear, it means you are pregnant; if no color line appears, it means the test is invalid or failed.

There are three types of pregnancy test results

1. Negative (-): Only one purple-red band appears in the quality control area (C), and no purple-red band appears in the test area (T). This indicates that the woman is not pregnant.

2. Positive (+): Two purple-red bands appear, one in the test area (T) and the other in the quality control area (C). This indicates pregnancy.

3. Invalid: No purple-red band appears in the quality control area (C), indicating incorrect operation process or the reagent strip has deteriorated and damaged.

Note: The color of the control line and the test line of the pregnancy test paper may appear darker or lighter depending on the hCG content in the urine. The result is determined according to the above standards.
