定义
Serology for 布鲁氏菌病 is a blood test to look for the presence of
选择的名字
Brucella serology; Brucella antibody test or titer
How the Test is Performed
A
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
Brucellosis is an infection that occurs from coming into contact with animals that carry brucella bacteria.
Your health care provider may order this test if you have signs or symptoms of 布鲁氏菌病. People who often come in contact with animals or meat are most likely to get this disease. 这包括:
- Slaughterhouse workers
- 农民
- 兽医
正常的结果
A normal (negative) result usually means you have not come in contact with the bacteria that causes 布鲁氏菌病. However, this test may not detect the disease at an early stage. Your provider may have you come back for another test in 10 days to 3 weeks.
Infection with other bacteria, such as 鼠疫的spp., 弗朗西斯氏菌属spp., 弧菌spp., certain immunizations can cause false-positive results.
Normal value ranges may vary slightly among different laboratories. Some labs use different measurements or test different samples. Talk to your provider about the meaning of your specific test results.
What Abnormal Results Mean
An abnormal (positive) result usually means you have come in contact with the bacteria that causes 布鲁氏菌病 or a closely related bacteria.
However, this positive result does not mean that you have an active infection. Your provider will have you repeat the test after a few weeks to see if the test result increases. This increase is more likely to be a sign of a current infection.
风险
There is little risk involved with having your blood taken. Veins and arteries vary in size from one person to another and from one side of the body to the other. Taking blood from some people may be more difficult than from others.
Other risks associated with having blood drawn are slight, but may include:
- Fainting or feeling lightheaded
- Multiple punctures to locate veins
- Hematoma (blood buildup under the skin)
- 大出血
- Infection (a slight risk any time the skin is broken)
