Currently, there are two types of processing in the cord blood market, manual and automated. Some companies choose to use manual processing systems while others have moved to automated processing systems.
Manual processing involves allowing the blood to sit for a period of time and then manually extracting cells from the middle of what has “settled” out from the cord blood. This method was the only method available for a long period of time and is very capable of collecting and harvesting necessary cells for transplant purposes. There are two potential problems however with manual processing. Manual methods recover only 40%-80% of cells necessary for transplant purposes and can potentially subject the cord blood to potential airborne contaminants.
Automated processing has avoided these potential problems by working in a completely closed system eliminating excess air contamination and, most importantly, allowing for up to 99% recovery of necessary cells for transplantation.
