After your child is born and his or her cord blood has been collected, it is sent to our FDA-approved lab. You can track the progress of your kit from the time it leaves your hospital room until the time it reaches our lab. Once the umbilical cord blood unit arrives, it undergoes a battery of tests to ensure viability, sterility, and volume.
To ensure the cord blood is free of contaminates, it is tested for aerobic and anaerobic bacteria and fungi. Also tested for during process is a complete blood count with differential, nucleated and mononucleated cell count, red blood type, a viability analysis, CD34 count, as well as other tests to confirm the cord blood unit is suitable for storage.
After the testing is complete, a CariCord representative will notify you to let you know that your baby’s cord blood has been processed and will tell you the processing date, the final cell count, and volume of the cord blood. The minimum amount of cord blood required for storage is 8 ml.
If a cord blood unit does test positive for any sterility issues, your doctor will be notified. Generally, the sample is still stored, however, it is placed in a special quarantine tank separate from other cord blood units to prevent any possibility of cross-contamination.
Testing is also performed on the maternal blood sample, also taken at the time of birth. The sample is tested for many infectious diseases such as HIV, Hepatitis B and C viruses, syphilis, and Cytomegalovirus (CMV), and more. Cord blood units may be rejected if the maternal sample tests positive for HIV, Hepatitis B or Hepatitis C, trypanosomiasis disease, or West Nile Virus. Any abnormal results are recorded on the cord blood sample and your doctor will be notified.
Currently, HLA typing is not performed initially on each cord blood unit. We do save a small portion that may be typed upon request, usually in the case of a possible transplant. Also, infectious disease markers are not tested for in the initial processing of the umbilical cord blood, as there is no licensed kit to test cord blood for infectious disease markers at this time.
CariCord, we want you to be assured that your baby’s cord blood is in good hands and that every step is taken to safeguard you and your family’s future with the proper testing, handling and storage of your cord blood unit.
