Can ovulation test strips detect early pregnancy? Authoritative experts are here to answer!

Women all know about ovulation test strips. Ovulation test strips can detect the level of hormones produced by the corpus luteum to determine whether the body has ovulated. Many women will use this method to determine the safe period. In fact, ovulation test strips can also test early pregnancy. Facts have proved that the test results are still very accurate, but the method must be correct. The following is a detailed introduction to the relevant knowledge of ovulation test strips.

First, can ovulation test strips detect early pregnancy?

The most popular method now is to use early pregnancy test strips to test early pregnancy. However, some people have asked whether ovulation test strips can detect early pregnancy. I can only show you what the functions of ovulation test strips are. Can ovulation test strips detect early pregnancy?

1. Generally speaking, we do not recommend using ovulation test strips to detect early pregnancy because its accuracy is very low. The principle of using ovulation test strips to test early pregnancy is that HCG has two chains, α and β. The structure of the α chain is basically similar to LH and FSH, and cross-reactions are prone to occur. Therefore, in medicine, β is generally used as the standard for determining whether pregnancy is present.

2. Because HCG and LH cross, ovulation test strips sometimes also react to early pregnancy. So before the early pregnancy test paper, the ovulation test paper had already detected early pregnancy. In fact, ovulation test strips are not accurate in detecting early pregnancy. The absence of a weak positive result on the ovulation test strip does not mean that you are not pregnant, because cross-reaction is not inevitable. Therefore, although many women want to use ovulation test strips to detect early pregnancy, given its low accuracy, we do not recommend using ovulation test strips to detect early pregnancy.

Second, how to detect early pregnancy with ovulation test paper

Ovulation test strips are a type of test strip that is more commonly used by female friends besides early pregnancy test strips. Ovulation test strips are a more convenient testing method for early pregnancy. So how do ovulation test strips detect early pregnancy? Let’s take a look at the specific operation methods.

1. Before the test, you need to use a clean and dry container to collect urine. Do not use morning urine. Doctors say the best time to collect urine is from 10 am to 8 pm. Try to use urine samples at the same time every day. Water intake should be reduced 2 hours before collecting urine, because diluted urine samples will hinder the detection of LH peak. Try to avoid diluting urine samples before the test to ensure its accuracy.

2. After collecting the urine sample, dip the end of the test strip with the arrow mark into the urine, take it out and lay it flat after about three seconds. Wait 10-20 minutes before observing the results. Doctors remind that the test results must be read within 30 minutes. If the time is too long or too short, the data may be inaccurate.

3. It is worth noting that the depth of the test paper inserted into the urine should not exceed the MAX mark line, otherwise it will affect the accurate reading and accuracy of the results.

Third, are ovulation test strips accurate in detecting early pregnancy?

1. Ovulation test strips are used to detect ovulation. If you use ovulation test strips to detect early pregnancy, it has its limitations. Even if it can detect whether you are pregnant, the accuracy will be reduced, which can easily lead to missed diagnosis or misdiagnosis. Therefore, generally speaking, using ovulation test strips to detect early pregnancy may not be very accurate. Therefore, if you want to test early pregnancy, you can use early pregnancy test strips. Early pregnancy test strips are used specifically to test whether you are pregnant and have relatively high accuracy. Generally, ovulation test strips are used to test whether you have ovulated in the middle of your period. Early pregnancy test strips are used to test whether you are pregnant after menstruation stops. There are obvious differences between the two, so remember to distinguish them accurately.

2. HCG has two chains, α and β. The structure of the α chain is basically similar to LH and fsh, and is prone to cross-reaction. Therefore, in medicine, β is generally used as the standard for determining whether pregnancy occurs. Because HCG and LH cross, ovulation test strips sometimes also react to early pregnancy. Therefore, before the early pregnancy test paper, the ovulation test paper had already detected early pregnancy. Generally speaking, ovulation test strips can detect pregnancy 2 days earlier than early pregnancy test strips, but the results are not 100% accurate.

3. Why are there errors when using ovulation test strips to detect early pregnancy?

Perhaps many women have used their own experience to prove the fact that ovulation test strips can detect early pregnancy. However, it should be noted that a weak positive result with an ovulation test strip does not necessarily mean that you are pregnant. This is mainly because normal people ovulate once a month, and the LH peak only appears once before ovulation each month. Apart from this, LH generally remains stable at a low level without much change during the rest of the month. So normally, LH should not be detected to be elevated more than ten days after ovulation. However, some people's LH levels are always high, and after ovulation, there is always a weak positive LH. Some people sometimes have abnormal LH fluctuations when their menstruation is about to come. Therefore, if you judge pregnancy based on only a weak positive result on the ovulation test paper, you may make a wrong judgment.
