Test Code LAB1754 Cytology, Body Fluid/Other

Useful For

Cytologic evaluation is a diagnostic aid for detection of cancer, its precursors, and inclusion bodies. It is useful for detection in asymptomatic patients, in high-risk groups, and in patients with clinically-suspected carcinomas. It is also an aid in detection of benign processes such as opportunistic infections.

Specimen Requirements

Specimen Type: Body fluid

Sources: Pleural or Peritoneal

Container/Tube: Screw-capped, plastic container

Specimen Volume: 20-50 mL

Collection Instructions:

  1. Collect fluid and place in a sterile screw-capped container.
  2. Add an equal amount of CytoLyt to fix specimen.  If no preservative is used, keep specimen refrigerated.
  3. Label container with patient’s name (first and last), date and actual time of collection, source and site of specimen, physician’s name, and hospital identification number (if applicable).
  4. Place specimen in plastic specimen bag with request form inserted into pocket separate from specimen, and, if possible, deliver specimen to Cytology Laboratory.

 

Specimen Type: Body fluid

Sources: Culdocentesis, cyst, pericardial, pericardiocentesis, synovial, or peritoneal washing.

Container/Tube: Screw-capped, plastic container

Specimen Volume: 20-50 mL

Collection Instructions:

  1. Collect fluid and place in a sterile screw-capped container.
  2. Label container with patient’s name (first and last), date and actual time of collection, source and site of specimen, physician’s name, and hospital identification number (if applicable).
  3. Place specimen in plastic specimen bag with request form inserted into pocket separate from specimen.
  4. Refrigerate at  2° C to 8° C until delivery to the Cytology Laboratory.

 

Specimen Type: Spinal fluid

Container/Tube: Screw-capped sterile tube

Specimen Volume: 1-3 mL

Collection Instructions:

  1. Prefixation with alcohol is not recommended, alcohol may precipitate protein present in spinal fluid.
  2. If there is a delay in transport, add an equal amount of CytoLyt to fix specimen.
  3. Label container with patient’s name (first and last), date and actual time of collection, source and site of specimen, physician’s name, and hospital identification number (if applicable).
  4. Place specimen in plastic specimen bag with request form inserted into pocket separate from specimen.
  5. Deliver specimen to Cytology Laboratory. Do not send by pneumatic tube. Fresh spinal fluid must arrive immediately after collection.
  6. "Examine for Tumor Cells or Leukemia Cells" must be indicated on request form for Cytology processing. Specimen cannot be processed without out this information.

 

Specimen Type: Gastrointestinal brushing or secretion

Patient Preparation:Patient should be fasting overnight and should not eat the morning of the collection.

Container/Tube: Screw-capped, plastic container

Specimen Volume: Adequate amount

Collection Instructions:

1. Collect gastrointestinal brushing or secretion and place in container.

2. Add an equal amount of CytoLyt to fix specimen.

3. Label container with patient’s name (first and last), date and actual time of collection, source and site of specimen, physician’s name, and hospital identification number (if applicable).

4. Place specimen in plastic specimen bag with request form inserted into pocket separate from specimen, and, if possible, deliver specimen to Cytology Laboratory.

 

Specimen Type: Breast/Nipple discharge

Container/Tube: Container with CytoLyt fixative

Specimen Volume: Adequate amount

Collection Instructions:

1. Support areola and nipple with 1 hand. Gently strip sub-areolar area going towards nipple.
2. Wipe areolar area with alcohol soaked gauze.
3. Squeeze nipple to produce a drop of secretion.
4. Wipe away first drop of secretion.
5. Express discharge into container.

6. Label container with patient’s name (first and last), date and actual time of collection, source and site of specimen, physician’s name, and hospital identification number (if applicable).

7. Place specimen in plastic specimen bag with request form inserted into pocket separate from specimen, and, if possible, deliver specimen to Cytology Laboratory

 

Specimen Type: Oral lesion

Container/Tube: Container with CytoLyt fixative
Specimen Volume: Adequate amount
Collection Instructions:

  1. Cleanse mouth prior to collection by having patient rinse area thoroughly with distilled water.
  2. Scrape area or lesion with wooden or plastic tongue depressor.
  3. Rinse immediately in container with CytoLyt fixative.
  4. Label container with patient’s name (first and last), date and actual time of collection, source and site of specimen, physician’s name, and hospital identification number (if applicable).
  5. Place specimen in plastic specimen bag with request form inserted into pocket separate from specimen.
  6. Specimen must be hand delivered to a technician in the Cytology Department and arrive within 15 minutes of collection as cellular breakdown occurs rapidly.

3. Unlabeled specimen

4. No doctor’s name given

5. Spilled specimen

Reference Values

Diagnostic interpretation is based on morphologic cellular changes and is reported to the clinician using descriptions, comments, and recommendations when appropriate.

 

Note: Cells observed in the specimen received may not represent the true nature of the lesion or clinical conditions because of sampling fallibility. A negative cytologic diagnosis does not rule out the possibility of an existing malignancy.

Interpretation of cells found in spinal fluid is difficult due to the small volume of specimen normally received, the paucity and distortion of cells, and commonly, extensive cellular degeneration resulting from the lapse between time of cellular exfoliation and collection of the specimen. The presence of contaminants from any source may be disastrous to interpretation and should be avoided both during specimen collection and specimen processing.
