What is the Weil-Felix test normal range

The Weil-Felix test is a blood test that is used to detect antibodies to certain rickettsial bacteria. Rickettsial bacteria are responsible for a variety of diseases, including Rocky Mountain spotted fever, typhus, and Q fever.

The normal range for the Weil-Felix test is a titer of 180 or less. This means that if your titer is 180 or less, you do not have antibodies to the rickettsial agent and are considered negative for the disease.

A titer of 1160 or higher is considered positive for the Weil-Felix test. This means that you have antibodies to the rickettsial agent and may have an active infection. However, it is important to note that a positive Weil-Felix test does not always mean that you have a rickettsial infection. There are other conditions that can also cause a positive Weil-Felix test, such as malaria, typhoid fever, and leptospirosis.

If you have a positive Weil-Felix test, your doctor will likely order additional tests to confirm the diagnosis of a rickettsial infection. These tests may include a blood culture, a PCR test, or a serologic test.

The Weil-Felix test is a useful tool for diagnosing rickettsial infections, but it is important to remember that it is not 100% accurate. If you have a positive Weil-Felix test, it is important to work with your doctor to get a definitive diagnosis and treatment plan.

Here are some additional things to keep in mind about the Weil-Felix test normal range

* The normal range for the Weil-Felix test may vary slightly from lab to lab.
* The titer of the Weil-Felix test can change over time. If you have a positive Weil-Felix test, it is important to get retested periodically to see if the titer is increasing or decreasing.
* The Weil-Felix test is not as sensitive or specific as some other tests for rickettsial infections. This means that it may not always be able to detect a rickettsial infection, and it may also give false positive results.
