Campylobacter serology test

定义

Campylobacter serology test is a blood test to look for 抗体 to bacteria called campylobacter.

How the Test is Performed

A 血液样本 是必要的.

The sample is sent to a lab. There, tests are done to look for 抗体 to campylobacter. Antibody production increases during the infection. When the illness first starts, few 抗体 are detected. For this reason, blood tests need to be repeated 10 days to 2 weeks later.

How to Prepare for the Test

There is no special preparation.

How the Test will Feel

When the needle is inserted to draw blood, some people feel moderate pain. Others feel only a prick or stinging. Afterward, there may be some throbbing or a slight bruise. This soon goes away.

Why the Test is Performed

This test detects the presence of 抗体 to campylobacter in the blood. Campylobacter infection can cause diarrheal illness. A blood test is rarely done to diagnose campylobacter diarrheal illness. It is used if your health care provider thinks you are having complications from this infection, 如 reactive arthritis or Guillain-Barré syndrome.

正常的结果

A normal test result means no 抗体 to campylobacter are present. This is called a negative result.

Normal value ranges may vary slightly among different laboratories. Talk to your provider about the meaning of your specific test results.

What Abnormal Results Mean

An abnormal (positive) result means that 抗体 against campylobacter have been detected. This means you have come in contact with the bacteria.

Tests are often repeated during the course of an illness to detect a rise in antibody levels. This rise helps to confirm an active infection. A low level may be a sign of a previous infection rather than current disease.

风险

Veins and arteries vary in size from one person to another and from one side of the body to the other. Obtaining a 血液样本 from some people may be more difficult than from others.

Other risks associated with having blood drawn are slight, but may include:

• 大出血
• Fainting or feeling lightheaded
• Hematoma (blood buildup under the skin)
• Infection (a slight risk any time the skin is broken)
