Special Stain, Modified Giemsa (Diff-Quick)
Also known as: M GIEMS SS
Use
This test provides a histochemical staining service (Modified Giemsa / Diff‑Quick) for tissue or cellblock samples in anatomic pathology. It is performed as a “stain and return” (technical) service, enabling visualization of cellular or microbial features using the Modified Giemsa (Diff‑Quick) stain.
Special Instructions
An ARUP Anatomic Pathology Test Request Form (#32960) is recommended for ordering (electronic or using the physical form). The specimen must be fixed in formalin and paraffin‑embedded (cells prepared into a cellblock). Transport using a tissue block or at least 2 unstained (3‑ to 5‑micron thick), positively charged slides in a tissue transport kit (ARUP supply #47808). Submit electronic request or use form #32960 if electronic ordering is not available.
Limitations
This test is a technical stain and return service only; no interpretive or diagnostic commentary is provided. Unacceptable specimens include non‑representative tissue types or depleted specimens. Slides or blocks must be protected from excessive heat. Frozen specimens are unacceptable. Degraded or processed incorrectly specimens may compromise staining quality.
