Anti Nuclear Antibody Test

If you are having troubles getting pregnant, you may decide to have an anti nuclear antibody test to check the levels in your body. It is a simple blood test which can be performed at your fertility clinic. Blood is drawn from your arm and sent to a laboratory for examination.

What do the results mean?

When you get your results back from your anti nuclear antibody test, your health care provider will go over them with you. These results will help you to determine what your next step in fertility treatment will be. Anti nuclear antibodies are measured in titers. This is a measurement of how much your blood can be diluted before no antibodies can be seen.

Normal levels are typically under 1:20, though 1:40 is also acceptable. Levels above 1:40 indicate a high presence of anti nuclear antibodies in your blood. This may be contributing to your infertility.

After the test

If your results are normal, then anti nuclear antibodies are probably not playing a role in your fertility troubles. Further testing may be required to get to the root of the problems.

If you do have high levels, than you might consider treatment to help lower them. This can help to increase your chances of conceiving a child. Typical treatment involves the medication prednisone, which has proven highly effective for many women. In fact, up to 54% of women on prednisone conceive a child in their next treatment cycle. Speak with your health care provider for more information.
