Does a positive urine test mean pregnancy?

There are actually many ways for girls to know whether they are pregnant, and urine test is one of them. If a woman's urine test is positive, she should consider whether she is pregnant. But does it mean that she is definitely pregnant? This issue is of concern to many mothers who are preparing for pregnancy, especially those who have always wanted a baby but have never been able to conceive. So, does a positive urine test mean pregnancy?

Positive urine test indicates pregnancy

Urine pregnancy test, also known as urine test, is a method used by most women today to detect early pregnancy. Today's early pregnancy test strips are more sensitive than in the past, and early pregnancy can be detected about 30 days after menstruation. In recent years, medical abortion has become common. Some people take abortion pills on their own after a positive urine test, which leads to many unnecessary adverse effects. This is because two bars do not necessarily mean a normal pregnancy.

There are several types of urine pregnancy test results:

1. If the test result is positive, a red reflection line will appear on the test line and the comparison line. In other words, there will be two green lines on the pregnancy test paper. If the test line is darker than the comparison line, it is a strong positive result, indicating that the pregnancy has been going on for some time.

2. If the test is negative, only a bright red reflection line will appear at the comparison line.

3. If there is no bright red reflection line on the invalid test paper, or only one reflection line appears at the detection line, it means that the test is unsuccessful or the test paper is invalid, and you need to try again with a new test paper.

Why is the urine positive when I am not pregnant?

If the urine test is positive, there is a high possibility of pregnancy (it cannot be confirmed that the possibility of positive is eliminated). In addition, there are generally two possibilities for a positive HCG urine test: one is miscarriage during pregnancy; the other is ectopic pregnancy.

If the pregnancy is short (usually more than 5 weeks), only ultrasound can detect whether there is a gestational sac (intrauterine). If the time is short, ultrasound may not be able to see it. Therefore, the time you often talk about is important. It is recommended to do a blood β-HCG test. According to the actual data, you can analyze and judge how long the pregnancy has lasted, so as to better judge whether your pregnancy date is accurate.

If it is a miscarriage, the blood HCG level will decrease, and it will become worse compared with the number of days of pregnancy. Only when the pregnancy is more than 6 weeks (referring to the time when sperm and egg combine, the menstrual period should be more than 2 months) can it be considered as miscarriage or incomplete miscarriage. However, if there is miscarriage, there should be bleeding and expulsion of the gestational sac after menstruation.

Common Problems with HCG Measurement

1. Distinguish between normal and abnormal pregnancy: HCG changes during pregnancy show a bimodal curve. According to the normal changes in HCG concentration values, if the first HCG is within the normal range, 79% of people can become pregnant to full term. If the first HCG is significantly lower than normal, 92% of pregnancies will fail.

2. Diagnosis and treatment of miscarriage: In incomplete miscarriage, there is still embryonic tissue remaining in the uterus, and HCG is judged to be positive. In complete miscarriage or fetal death, HCG may be negative. If HCG is below 2500U/L and gradually decreases, there is a possibility of miscarriage or fetal death. When it drops to 600U/L, miscarriage is inevitable. If HCG in urine continues to decrease, it indicates that the pregnancy maintenance is ineffective. On the contrary, it indicates that the pregnancy maintenance is successful. Blood cell HCG should recover 4 days after giving birth or 13 days after an abortion. If this condition is not met, the possibility of abnormality should be considered.

3. In cases of malignant hydatidiform mole, choriocarcinoma and testicular teratoma in men, the urine HCG component is very high, reaching 100,000 to tens of millions of international units.

4. Others: HCG changes differently during pregnancy toxemia, and the value is usually high; HCG components increase during multiple pregnancies.

What does a positive hcg test mean? A positive hcg test means you are pregnant and a new life is about to be born. However, during pregnancy, the hCG values ​​of many expectant mothers do not reach the standard range or exceed it. These are very dangerous and should be paid attention to. Therefore, expectant mothers should also properly understand the problems of HCG measurement.
