Clinical Information
CD43 (cluster of differentiation 43) is expressed by T lymphocytes and myeloid cells including granulocytes and precursors, monocytes, macrophages, histiocytes, plasma cells and megakaryocytes. In normal tonsil, CD43 will mainly show staining in T lymphocytes, histiocytes and plasma cells.
Interpretation
This test does not include pathologist interpretation, only technical performance of the stain. If interpretation is required, order PATHC / Pathology Consultation for a full diagnostic evaluation or second opinion of the case.
The positive and negative controls are verified as showing appropriate immunoreactivity. If a control tissue is not included on the slide, a scanned image of the relevant quality control tissue is available upon request; call 855-516-8404.
Interpretation of this test should be performed in the context of the patient's clinical history and other diagnostic tests by a qualified pathologist.
