Tick-borne relapsing fever Borrelia group, antibody detection to 4 recombinant protein groups, by immunoblot, IgM
CPT4 code
Name of the Procedure:
Tick-borne Relapsing Fever Borrelia Group Antibody Detection to 4 Recombinant Protein Groups, by Immunoblot, IgM
Summary
This procedure is a blood test that checks for antibodies, specifically IgM, against the Borrelia bacteria, which causes tick-borne relapsing fever. It uses an immunoblot method to detect the immune response to four distinct Borrelia proteins.
Purpose
This test is used to diagnose tick-borne relapsing fever, a bacterial infection transmitted by ticks. It aims to determine if a patient has been exposed to Borrelia bacteria by detecting specific antibodies, which can help guide appropriate treatment.
Indications
- Patients exhibiting symptoms such as recurring fever, headache, muscle and joint aches, and nausea following a tick bite.
- Individuals who have been in areas where tick-borne relapsing fever is common.
- Unexplained recurrent fevers with no clear diagnosis.
Preparation
- No special preparation like fasting is required for this blood test.
- Patients should inform their healthcare provider about any medications they are taking.
- It’s helpful to provide a complete medical history, including any recent travel or tick exposures.
Procedure Description
- A healthcare professional will draw a blood sample from a vein in the arm.
- The blood sample is sent to a laboratory where it is tested using immunoblot technology.
- In the lab, the sample is exposed to recombinant proteins that mimic the Borrelia bacteria.
- If IgM antibodies are present, they will bind to these proteins, indicating exposure to the bacteria.
- Lab technicians will analyze the results to detect the presence and concentration of the specific antibodies.
Duration
The blood draw usually takes about 10-15 minutes. Laboratory analysis may take several days to a week.
Setting
This procedure is performed in a healthcare provider's office or a clinical laboratory.
Personnel
- Phlebotomist or nurse to draw the blood sample.
- Laboratory technician or technologist to perform the immunoblot test.
Risks and Complications
- Minor risks include bruising or discomfort at the blood draw site.
- Rarely, infection or excessive bleeding might occur.
Benefits
- Accurate diagnosis of tick-borne relapsing fever.
- Quick identification of the infection allows for prompt treatment.
- Non-invasive and relatively simple to perform.
Recovery
- No significant recovery needed.
- Patients may resume normal activities immediately after the blood draw.
- Follow-up with the healthcare provider to discuss results and treatment options, if necessary.
Alternatives
- Other antibody tests like ELISA (enzyme-linked immunosorbent assay).
- PCR (polymerase chain reaction) tests to detect Borrelia DNA.
- Blood smear microscopy to directly observe the bacteria.
- Pros of alternatives include different sensitivity and specificity rates; cons include varying availability and cost.
Patient Experience
- Patients may experience a brief discomfort during the blood draw.
- Following the procedure, some might have minor bruising or soreness at the puncture site.
- Anxieties related to blood draws can be alleviated by the healthcare team through explanations and comfort measures.
- Pain is minimal and usually managed with basic aftercare instructions.
