Use
Histologic diagnosis
Special Instructions
Test request form must state operative diagnosis and source of specimen. Labcorp test number is for tracking purposes only. Additional test numbers may be entered upon receipt of specimen(s) at the test facility.
Limitations
The accuracy of histopathological diagnosis is reliant on the quality of the tissue sample provided. Inadequate fixation, improper labeling, or compromised samples may limit the accuracy. Absence of clinical history or improper handling could lead to misinterpretation. The test does not identify every possible condition, and additional confirmatory or reflex tests may be needed to support the initial findings.
