Collection Process of required samples in the delivery hospital by trained healthcare professionals

Maternal Blood: 3 tubes of maternal blood will be taken from mummy’s peripheral vein upon admission for delivery to test for infectious diseases.
Cord Blood: Cord blood is drawn by gravity into a collection bag after your baby is safely born and the cord has been clamped and cut. It is a safe and pain-free procedure to both mother and baby, which is less than five minutes.
Cord Tissue: Cord tissue is collected into a container immediately after cord blood collection is done. It is also a safe and pain-free procedure for both mother and baby, which is less than 2 minutes.
To all the expectant parents, all healthcare professionals in SG 10 maternity hospitals are trained by Cryoviva SG on the collection process.
