Venous Blood Samples

Routine chromosome investigation requires 4ml blood taken into a heparin tube.

The blood can be kept at 4 °C (NOT frozen) until sent to the laboratory.

The clinical findings should be clearly stated on the referral form as the clinical diagnosis can influence the number and extent of specialised tests which will be performed on the chromosomes.

If in doubt please contact the laboratory.
