Interleukin 2 Receptor

Interleukin 2 Receptor

The Interleukin 2 Receptor (IL-2R) test is an essential diagnostic tool for assessing immune function by measuring soluble interleukin-2 receptor levels in serum or cerebrospinal fluid (CSF). This test aids in diagnosing and understanding immune, infectious, allergic, and inflammatory disorders. Specimens, either serum or CSF, must be collected and frozen promptly to maintain cytokine integrity. The test utilizes a quantitative multiplex bead assay, allowing for precise measurement of multiple cytokines simultaneously. Elevated IL-2R levels often indicate an active immune response, useful in diagnosing conditions like sarcoidosis and autoimmune diseases. The test's clinical significance lies in its ability to monitor disease progression and treatment efficacy. It is performed in CLIA-certified labs with a typical turnaround time of 1-4 days. As research progresses, the IL-2R test's role in clinical diagnostics is expected to expand, offering deeper insights into immune-related conditions.

Purpose of the test

The Interleukin 2 Receptor (IL-2R) test is essential for diagnosing immune, infectious, allergic, or inflammatory disorders. It measures soluble IL-2 receptors in serum or CSF, aiding in understanding immune function and disease diagnosis.

- Specimen Collection:
- Serum: Draw blood into a red-top or serum gel tube, spin down, freeze immediately.
- CSF: Transfer 1 mL to a transport tube, freeze immediately.

- Methodology:
- Uses a quantitative multiplex bead assay for precise cytokine measurement.

- Clinical Significance:
- Elevated IL-2R levels indicate immune response, aiding in diagnosing conditions like sarcoidosis.

Who Should Get Tested

The Interleukin 2 Receptor (IL-2R) test is essential for diagnosing immune-related disorders. It measures soluble IL-2 receptors in serum or cerebrospinal fluid (CSF) to evaluate immune function. Key points include:

- Specimen Collection: Requires serum or CSF, frozen immediately to preserve cytokine integrity.
- Methodology: Uses a quantitative multiplex bead assay for precise results.
- Clinical Significance: Elevated IL-2R levels indicate immune response, aiding in diagnosing conditions like sarcoidosis.
- Practical Considerations: Conducted in CLIA-certified labs with a 1-4 day turnaround.
- Future Directions: Expanding use in autoimmune disease diagnosis and monitoring.

Blood Test Preparation Guidelines

Time of day

It is recommended to schedule your appointment for blood tests in the morning hours between 7:00-10:00.

Fasting

It is recommended to fast for approximately 12 hours before blood sampling. The last meal of the previous day should ideally be consumed around 6:00 p.m. On the day before the test, avoid heavy and fatty meals as well as alcohol.

Stay hydrated

Drinking water prior to testing can help with sample collection.

Other factors

Tests should not be performed after a sleepless night or intense physical activity. It is recommended to avoid exercise and stress immediately before blood collection and to not smoke. A short rest is recommended.

Medications and supplements:

Blood samples should be collected before the morning dose. Some drugs can interfere with test results. Consult with your doctor whether you can delay your dose because of lab tests.

Biotin supplements:

High doses of biotin supplements can affect test results, causing false elevation or reduction. It's recommended to avoid taking biotin for at least 72 hours before blood collection. If you are taking biotin, inform the personnel collecting the blood so that they can provide specific instructions.

Interpreting Test Results

Understanding test results from the Interleukin 2 Receptor (IL-2R) test is crucial for diagnosing immune-related disorders. Elevated IL-2R levels often indicate an active immune response, aiding in the diagnosis of conditions like sarcoidosis and autoimmune diseases. Key points include:

- Elevated Levels: Suggest ongoing immune activity.
- Clinical Use: Helps diagnose and monitor disease progression.
- Sensitivity: Particularly useful in identifying sarcoidosis.
- Diurnal Variation: Levels may fluctuate; consistent timing is recommended for comparisons.

This test is vital for understanding immune function and disease progression.
