Cervical Conization/Wide Skin Excision Jars – Farmington Hills Only

Please contact the Farmington Hills Anatomic Pathology Laboratory if assistance with ordering is needed.


The following supplies are needed for this testing procedure.

  • Wide mouth plastic jars with tight sealing lids filled with several inches of molten paraffin.
  • Straight pins with colored heads.

Specimen Collection Criteria

Collect: Tissue specimen in an appropriate container, covered with 10% zinc formalin, as described below:

  1. Place the specimen upon the paraffin surface and secure into the wax with the straight pins.
  2. By using several pin colors, the specimen can be oriented. For example: 2 red pins can secure the endocervical border and 2 blue pins can secure the ectocervical border of the conization specimen.
  3. Fill the jar with 10% Zinc Buffered Formalin, 10 to 20 times the volume of the specimen.
  4. Affix a label on the outer surface of the jar rather than the lid.
  5. The label must have the patient name, medical record number or social security number, date, and specimen site.
  6. Complete the Pathology Requisition Form. Indicate specimen orientation by describing colored pin locations.
  7. Transport the specimen to the Laboratory.
