Likewise, people ask, why do doctors not want to test for Lyme disease?
Testing Limitations Makes Lyme Disease Difficult to Detect
And because most tests measure antibodies to Borrelia burgdorferi – not the organism itself – patients sometimes test positive even if the organisms are no longer present.
Beside above, will a regular blood test show Lyme disease? You do not usually need tests to show that you have Lyme disease. In most cases, there's a clear sign of Lyme disease—a painless, spreading rash that often grows to look like a bull's eye. If you have this rash, and you recently had a tick bite or were in an area known for Lyme disease, you don't need a test.
One may also ask, why is the lab testing not definitive for Lyme disease?
Antibodies can take several weeks to develop, so patients may test negative if infected only recently. Antibodies normally persist in the blood for months or even years after the infection is gone; therefore, the test cannot be used to determine cure.
Can you have Lyme disease and never test positive?
There may not have been time for antibodies to develop; the immune system may be suppressed; or the person may be infected with a strain the test doesn't measure. Lyme disease is known to inhibit the immune system and 20-30% of patients have falsely negative antibody tests.
