Lyme Disease Antibody with Reflex to Antibodies IGG & IGM Blot
- (QUEST DIAGNOSTICS)Description:
Lyme disease is caused by a bacterium borrelia burgdorferi and is transmitted by ticks. The screening test is high sensitivity for antibody detection. Immunoblot testing qualitatively examines with high specificity antibodies in a patient#s specimen. Immunoblot testing is appropriate for confirming a detected screening result. Lyme Disease Antibodies (IgG, IgM) Immunoblot Confirmation is ONLY performed when the Lyme Disease Antibody screening is positive.
Aids in the diagnosis of acute or chronic infection with the lyme disease agent.
Lyme disease is an infection caused by the bite of an infected tick. The disease often begins as a rash. If you don#t get treatment, the infection can cause serious nerve or heart problems as well as a disabling type of arthritis (pain and swelling in one or more joints caused by inflammation).
Combination of IgM and IgM/IgG testing has the potential to provide the earliest and the broadest time window for serological detection. Immunoblot confirmation is recommended for positive results and is ONLY performed when the Lyme Disease Antibody screening is positive.
The CDC currently recommends a two-step process when testing blood for evidence of antibodies against the Lyme disease bacteria. Both steps can be done using the same blood sample.
The first step uses a screening procedure. If this first step is negative, no further testing of the specimen is recommended.
If the first step is positive or indeterminate (sometimes called "equivocal"), the second step should be performed. The second step uses a test called an immunoblot test. Results are considered positive only if the screening and the immunoblot are both positive.
The two steps of Lyme disease testing are designed to be done together. CDC does not recommend skipping the first test and just doing the Immunoblot. Doing so will increase the frequency of false positive results and may lead to misdiagnosis and improper treatment.
If the screening test is negative, the Immunoblot will not be performed and you will not receive the bands with your results.
A significant deviation from the normal range may require further evaluation by your physician.Includes: Lyme Disease Antibody, screening with Reflex to Antibodies IGG & IGM Immunoblot
Lyme Disease Antibodies (IgG, IgM) Immunoblot Confirmation is ONLY performed when the Lyme Disease Antibody screening is positive.
Note: Confirmation testing is performed on reactive results only if initial values fall within a designated range requiring additional confirmation.
