Special Instructions
Ensure to state the patient's age on the test request form, as age-related reference ranges are important for result interpretation.
Limitations
This test is not suitable for samples containing rheumatoid factor, paraproteins, or other circulating immune complexes (CICs) due to unpredictable nonspecific light scatter.
