Rheumatoid Factor Interference in Dual Immunoassays: False-Positive Procalcitonin and CK-MB Results

Key Result

The provided text contains web shop instructions rather than the clinical paper on rheumatoid factor interference in dual immunoassays.

Key Points

• The research aims to understand how high levels of rheumatoid factor affect dual immunoassays for procalcitonin and CK-MB.
• Investigation of high-titer rheumatoid factor effects on immunoassays
• Conducting dilution tests to assess interference
• Evaluation of alternative platforms
• Implementation of rheumatoid factor blocking protocols for testing
• High-titer rheumatoid factor caused significant false-positive results in procalcitonin and CK-MB assays
• Dilution and RF blocking reduced misdiagnoses
• Recommended RF interference protocols were necessary for accurate lab results
