SUPPLIES:
1. Standard endoscopy equipment
2. Clean plastic specimen container(s)
3. Specimen Requisition
4. Specimen Bag with a biohazard label
COLLECTION PROCEDURE:
Using standard endoscopy technique, lavage the area of interest using a physiologic solution. Aspirate the solution and place in a clean specimen container. Label the container with the correct patient information and submit FRESH, WITHOUT FIXATIVE, with the completed request form to your lab. If transport of the specimen will be delayed, the specimen should be refrigerated until transport to the lab.
UROLOGIC WASHINGS
INDICATIONS:
Detection of suspected malignancy utilizing lavage specimens obtained from cystoscopy (bladder washing, urethral washings); staging of urologic malignancies.
SPECIMEN REQUIRED:
10 ml (or more) of an appropriately collected cystoscopically derived specimen.
SUPPLIES:
1. Standard cystoscopy equipment
2. Clean collection container of appropriate size
3. Specimen Requisition
4. Specimen Bag with a biohazard label
COLLECTION PROCEDURE:
1. Using standard cystoscopy technique, obtain washing specimens, carefully denoting specific specimen sites for each specimen on the requisition.
2. Submit the specimen FRESH, WITHOUT FIXATIVE to your lab (within 12 hours) along with the completed cytology request form. If transport or processing will be delayed, the specimen should be refrigerated.
3. If DNA ploidy studies are desired, please indicate on the requisition form.
NOTE: Current laboratory policy is to perform DNA ploidy studies only on specimens that show abnormal cytologic findings. If the cytology portion of the examination is negative, DNA ploidy studies will be canceled by the pathologist unless otherwise specified by the submitting physician.
Complete test requisition including last and first name of patient, patient’s date of birth and social security number, body site, and source of specimen collected. Label specimen container (using the labels provided on the requisition) with patient’s first name and last name, and body site/source. The container must have at least two (2) unique identifiers.
