Lab tests are helpful mostly in the later stages of disease. Early they may give false results. People who have been sick with Lyme disease for less than a month may have negative blood test, because they still have to develop antibodies to the disease. Also, in early Lyme disease, patients who take antibiotics for other reasons may never develop a positive Lyme disease test. Blood test is almost always positive in patients who sick for over month without antibiotics.
Swelled joints or nervous system symptoms may require special tests. Joint fluid or spine fluid aspiration helps to recognize the condition.
How is Lyme disease treated?
Most cases of Lyme disease are treated with several weeks of antibiotics. Early Lyme disease requires 14 to 30 days of antibiotics. Antibiotics usually are given by mouth. If the nervous system is involved, antibiotics may need to be given intravenously. Take all the drugs, which your doctor prescribed, according to instruction. To prevent spreading the infection to joints, heart and nervous system do not stop taking the medicine. Call your doctor and discuss if you have some problems with the drug. Blood tests are not very useful to check your treatment.
