Can Antigen Tests Detect Pregnancy?

Pregnancy tests have been around for centuries, but the use of antigen tests for detecting pregnancy is a relatively new development. Antigen tests have been used to detect infections, such as with the flu, but can it also detect pregnancy? Here, we will explore what antigen tests are and if they can accurately detect pregnancy.

What Are Antigen Tests?

Antigen tests are a type of test used to detect the presence of a specific antigen in a person or material sample. The antigen is a molecule that can trigger an immune response and can be either a protein, carbohydrate, or other substance. An antigen test may be used to detect the presence of a virus, bacteria, fungi, or other microorganism in a sample.

Can An Antigen Test Detect Pregnancy?

Currently, there is no antigen test available specifically designed to detect pregnancy. However, the presence of certain hormones in the urine and blood of pregnant women can be identified by some antigen tests. The hormone hCG (human chorionic gonadotropin) is commonly used for pregnancy testing and is detectable by certain types of antigen tests.

What Are the Advantages of Using an Antigen Test for Pregnancy Testing?

Antigen tests have several advantages over other types of pregnancy tests. The tests are fast, accurate, and do not require a lab for results. Also, antigen tests allow for early detection of pregnancy, which can be especially helpful for women who may otherwise miss their window of opportunity for an early pregnancy test.

Are There Any Disadvantages to Using an Antigen Test for Pregnancy?

The main drawback to an antigen test is that they are not as sensitive as other types of pregnancy tests. In some cases, an antigen test may not detect a pregnancy until later in a woman’s cycle, thus making it less reliable in earlier stages of pregnancy. Additionally, some antigen tests may not detect every pregnancy and may give false positive results in some cases.


Antigen tests are a useful tool for quickly and accurately detecting certain infections, but they are not intended for use as pregnancy tests. While antigen tests can detect hormones associated with pregnancy, they are not as sensitive as other types of pregnancy tests, and may not be reliable for use in early stages of pregnancy. For best results, it is recommended to use a clinically approved pregnancy test.

If you have any concerns about pregnancy testing, it is always best to consult a healthcare professional for advice.
