About Cytopathology

Cytopathology is a subspecialty of pathology that evaluates cells on their own, without the surrounding tissue architecture that provides context in a biopsy. Rather than examining surgical tissue samples, cytopathologists assess cells collected through fine needle aspiration (FNA), brushings, and body fluid specimens such as urine, ascites, pleural fluid, and cerebrospinal fluid. This approach allows for rapid, minimally invasive assessment of a wide range of conditions, from infections to malignancies.

Our cytopathology services encompass fine needle aspiration (FNA) samples, urinary cytology, superficial masses, and body fluid evaluations, including pleural, peritoneal, and cerebrospinal fluid. We also evaluate brushings, washings, sputum, and other specimen types such as anal/rectal cytology and miscellaneous smears (Tzanck smear, nipple secretion, oral cytology, and ocular cytology). Please note that we DO NOT accept cervicovaginal (Pap) smears for cervical cancer screening.

Working with Sagis

Collection requirements vary by specimen type. FNA samples should be placed in cytology fixative, or RPMI if a hematolymphoid process is suspected. Fluid specimens are typically sent fresh and refrigerated, or in fixative depending on volume. Brushings and smears should be fixed immediately per our collection guide. Consult our full Cytopathology Specimen Collection Guide for reference.

When a case requires additional workup, our team correlates cytologic findings with histologic and immunocytochemical studies to maximize diagnostic clarity and support a confident, actionable diagnosis. When adequate material is available, we can also prepare a cell block, enabling additional studies such as immunohistochemistry and molecular testing.

Routine cytology cases are typically reported within 24 to 48 hours of specimen receipt.
