Chromosome Analysis, High Resolution
- High Resolution G-Banding
- Prophase Analysis
20 prophase to prometaphase cells are studied following cell synchronization. Two cells are karyotyped with the highest resolution.
Detect small chromosome abnormalities not detectable using routine methods; precise identification of abnormal chromosomes previously detected by routine methods
Culture of cells in special medium; colcemid arrest of cells in prometaphase stage of mitosis following cell synchronization techniques
10 mL (adult), 2 mL (pediatric)
Green-top (heparin) tube
Using sterile technique, collect 10 mL of blood into a sodium heparin tube or syringe. Invert the tube several times to prevent coagulation. Specimens must be sent the same day as collected and arrive in the laboratory within 48 hours of collection.
Specimen should be delivered immediately. Maintain specimen at room temperature. Specimen may be refrigerated if there is a delay in shipment. Do not freeze.
Causes for Rejection
Hemolysis; clotted specimen; use of improper anticoagulant; frozen specimen
Pertinent medical findings must accompany request for chromosome analysis.
