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.
Compliance Statement D: For laboratory tests using a manufactured RUO kit. This test was developed and its performance characteristics determined by ARUP Laboratories. The U. S. Food and Drug Administration has not approved or cleared this test; however, FDA clearance or approval is not currently required for clinical use.
