Specimen Collection Criteria

Collect: Fill the hub of a 10 cc luer lock syringe with cellular material from the target area, using a 23 gauge or smaller needle.

  • Localize lesion. 
  • Draw approximately 1/2 cc of air into a 10 cc luer lock syringe. Place needle into lesion and apply negative pressure in order to aspirate specimen. Continue to apply negative pressure until the hub of the syringe is full. 
  • Release negative pressure, withdraw the needle from the patient, and expel onto a slide provided by Cytology staff. The slide will be smeared with a second slide, one slide will be immediately spray fixed, and the other will be air dried. 
  • Rinse the needle in ThinPrep® Cytolyt. 
  • The Cytology staff will label the slides with patient name, birthdate and Cytology case number.  The needle rinse specimen container will be labeled with the EPIC specimen label which contains the patient name, birthdate, medical record number, and specimen source.
  • A separate pass is recommended for each additional test requested (i.e. flow cytometry, microbiology, mucin stain). Follow collection guidelines for specific testing (collection tube/solutions, handling and storage).
  • In house cytology specimens should be ordered in EPIC order entry. In the “additional orders” field input “CYTOLOGY, MEDICAL FNA” and fill in all appropriate fields. Label specimen container and requisition with EPIC specimen labels. 
  • All Cytology specimens must be accompanied by a requisition and must include the patient name, medical record and visit/CSN number, date of birth, date of specimen collection, pertinent patient history, ordering physician name and source of specimen. Place an EPIC specimen label on the requisition.

Physician Office/Draw Specimen Preparation

Maintain the fixed and air-dried slides or ThinPrep® Cytolyt needle rinse at room temperature (20-26°C or 68-78.8°F), and the tissue culture media (RPMI) needle rinse refrigerated (2-8°C or 36-46°F), prior to transport.  

Preparation for Courier Transport

Transport: Fixed and air-dried slides and ThinPrep® Cytolyt room temperature (20-26°C or 68-78.8°F), and tissue culture media (RPMI) needle rinse, refrigerated (2-8°C or 36-46°F).

Rejection Criteria

  • Improper labeling of specimen container, slides or requisition. 
  • Specimen not accompanied by requisition. 
  • Requisitions not accompanied by a specimen. 
  • Improper collection of specimen (such as improper fixation). 
  • Specimens contaminated with a foreign material.
