Name of the Procedure:

Immunofixation Electrophoresis (IFE); Serum

Summary

Immunofixation Electrophoresis (IFE) is a laboratory test that evaluates the presence of specific proteins in the blood serum. It is used to detect abnormal proteins and diagnose certain medical conditions related to abnormal protein production.

Purpose

Immunofixation Electrophoresis is used to identify and quantify abnormal proteins found in the blood. It helps in diagnosing and monitoring disorders such as multiple myeloma and other related blood disorders. The goal of the procedure is to determine the presence and type of abnormal protein patterns that are indicative of these conditions.

Indications

• Unexplained anemia
• Unexplained weight loss
• Frequent infections
• Bone pain
• Kidney dysfunction
• High levels of total protein or abnormal results on a standard electrophoresis test

Preparation

• No fasting is required.
• Continue taking prescribed medications, unless instructions are provided to adjust them.
• Inform the healthcare provider about any medications, supplements, or conditions that might affect the test results.

Procedure Description

1. A blood sample is drawn from the patient's vein, typically from the arm.
2. The blood sample is sent to a laboratory.
3. In the lab, the serum part of the blood is separated and applied to a gel.
4. An electric current is applied, which causes the proteins to move and separate based on their size and charge (electrophoresis).
5. Specific antibodies are then added to the gel to bind with particular proteins, making them visible.
6. The gel is analyzed and interpreted by a pathologist or laboratory technician.

Duration

The blood draw takes about 5-10 minutes. Laboratory processing and analysis typically take several hours to a few days.

Setting

Blood samples are usually collected in medical facilities such as hospitals, outpatient clinics, or diagnostic labs.

Personnel

• Phlebotomist or nurse for the blood draw
• Laboratory technician or pathologist for the analysis

Risks and Complications

• Minor bleeding or bruising at the puncture site
• Rare risk of infection at the puncture site
• Mild discomfort during blood draw

Benefits

• Accurate diagnosis of conditions involving abnormal protein production
• Helps in monitoring disease progression and response to treatment
• Non-invasive and straightforward procedure

Recovery

• Minimal to no recovery time required
• Patients can resume normal activities immediately after the blood draw
• Follow-up with the healthcare provider to discuss results and next steps

Alternatives

• Protein electrophoresis without immunofixation
• Serum Free Light Chain Assay (FLC)

• Bone marrow biopsy (more invasive)

  Each alternative has its own advantages and limitations, and the choice of test depends on the specific clinical scenario.

Patient Experience

• Slight pain or discomfort may be felt during the needle insertion for the blood draw.
• Some patients may experience mild bruising at the site which typically resolves in a few days.
• Overall, the procedure is quick and involves minimal discomfort.
