Intact N-Terminal Propeptide of Type 1 Procollagen
Also known as: PINP
Use
This test is used for measurement of Intact N-Terminal Propeptide of Type 1 Procollagen (PINP) levels in serum.
Special Instructions
Not provided.
Limitations
The test was developed by Labcorp and has not been cleared or approved by the FDA. It may exhibit limited specificity as it reflects bone turnover in general, and severe liver disease may affect its clearance from circulation, leading to elevated serum PINP levels. Heterophilic antibodies may cause erroneous results. Samples should be collected at the same time of day for subsequent evaluations due to diurnal variation.
