May aid in the evaluation of lung inflammation or injury in various types of interstitial lung disease (ILD).
Quantitative Enzyme-Linked Immunosorbent Assay
Allow specimen to clot completely at room temperature. Separate from cells ASAP or within 2 hours of collection. Transfer 1.5 mL serum to ARUP Standard Transport Tube. (Min: 0.5 mL)
Plasma, CSF, or other body fluids. Contaminated, heat-inactivated, hemolyzed, icteric, or severely lipemic specimens.
Ambient: 48 hours; Refrigerated: 2 weeks; Frozen: 1 month
Human Surfactant Protein D (SP-D) is a non-specific indicator of lung inflammation or damage. Elevated levels are associated with various types of interstitial lung diseases (ILD).
Abnormal SP-D results should be interpreted in the appropriate clinical context. A negative result does not rule out ILD.
