Specimen Collection Criteria

Collect: Bronchoalveolar Lavage (BAL) specimen in a sterile collection container under established endoscopic procedure. 

Dearborn, Farmington Hills, Grosse Pointe, Royal Oak, Trenton, Taylor, Troy, and Wayne
Add BAL specimen for Cytology to ThinPrep® CytoLyt solution vial(preferred). If requesting stain for lipid laden macrophages or PAS stain submit an unfixed specimen. Tightly seal the specimen container. (Minimum 5.0 mL, 10.0 mL preferred). 

  • Unfixed wash specimens should be immediately delivered to the Cytology Laboratory or refrigerated (2-8°C or 36-46°F) to slow deterioration of cell morphology.
  • Label the specimen container with EPIC specimen label with the patient name, date of birth, medical record, source of specimen, and date of test.
  • In house cytology specimens should be ordered in EPIC order entry. In the “additional orders” field input “MEDICAL CYTOLOGY REQUEST” and fill in all appropriate fields. Label specimen container and requisition with EPIC specimen labels which contain patient name, medical record number, source of specimen, test ordered, and date of test.
  • All Cytology specimens should 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.
  • It is imperative when submitting multiple specimens on the same patient that the labels on the requisition and vial match the correct EPIC order to ensure proper source/collection type to be assigned to the specimens.
