480327 DNA Ploidy, Paraffin Block |
| Clinical Use |
DNA ploidy analysis measures the chromosome content of the cancer cells. Diploid tumors have chromosome numbers of 46 chromosomes. Tumors that are not diploid suggest a major chromosomal disruption that serves as a poor prognostic sign. |

| Testing Sample Type |
PARAFFIN BLK OR 4 (4) micron unstained sections and 2 recut slides or H&E slide |
| Min Lab Testing Volume |
One paraffin block |
| Special Handling |
Specimen Container: Formalin fixed paraffin embedded tissue Formalin fixed paraffin embedded tissue block (preferred) Paraffin Block Bag (preferred) 50 micron unstained sections Formalin fixed, paraffin embedded tissue block Paraffin Block Bag Transport Temperature: Room temperature |
| Lab Notes |
Specimen should be fixed in 10% neutral-buffered formalin. Optimum fixation time is 12 to 24 hours, not to exceed 48 hours. |
| Methodology |
FC - Flow cytometry |
| Limitations |
Use of fixatives other than formalin may not yield equivalent or satisfactory results. No % S phase is reported for tumors analyzed by image cytometry. Small biopsies require image analysis of a 6 u tissue section. This test is not a diagnostic test for cancer.
