General Procedures

Registration

1 Registration

Upon registration with us, each customer will be assigned a barcode label with a registration number for all future identification. We will also provide each customer with a collection kit for their doctor's use.

Collection

2 Collection

After the baby is delivered, your doctor will collect the cord blood remaining in the umbilical vein and placenta using the sterilized closed-system collection bag set we provided. The collection process is user-friendly and painless.

Transport to Laboratory

3 Transport to Laboratory

Within 12 hours after notification from the customer, our dedicated transport staff will arrive the hospital with a temperature-controlled cell safe to collect the kit.

Verification of Information and Sample

4 Verification of Information and Sample

At the laboratory, our professional technician will verify the identity information and test the blood specimens for infectious diseases and blood grouping. Before processing, a small cord blood sample will be retrieved for stipulated tests.

Automated Processing

5 Automated Processing

We will remove red blood cells and plasma from the cord blood sample to obtain cord blood stem cells. This process will be performed by an advance automated cell recovery system which is functionally closed and sterile, ensuring effective contamination control and efficient recovery of the mononuclear cells (MNCs) from cord blood. After this process a small concentrated cord blood aliquot is prepared for stipulated tests.

Controlled-Rate Freezing and Storage

6 Controlled-Rate Freezing and Storage

After processing, we will add cryoprotectant to the processed cord blood unit and it will be ready for storage. The unit will undergo a slow freezing process at a controlled rate until it reaches -90'C before it is transferred to a vapour phase liquid nitrogen tank for long-term storage at -185 to -190'C.

On-going Quality Assurance

7 On-going Quality Assurance

We have put in place a biannual quality assurance program to ensure the good quality of cryopreserved cord blood units in each liquid nitrogen tank. Terminated cryopreserved units will be retrieved and thawed for quality tests including cell viability and cord blood stem cell count. Cord blood stem cell activities are also analyzed by performing colony formation unit (CFU) assay.

Cord / Cord Blood Collection Box

Collection BoxUpon registration with CRYOLIFE, each customer will be assigned a cord blood collection box (BB box) with a barcode label for their doctor's use.

The box contains tools required for cord blood collection: sterilized triple blood bag (with anticoagulant), vacuum tube for maternal blood collection, sterilization tools and other necessary materials. A client’s reminder and documents regarding cord blood collection are attached.

The BB box should be kept in cool dry place. Clients are obligated to notify her O&G physicians about the decision of cord blood banking. Please be reminded to take the BB box along to hospital for delivery. Pass the box to midwife or nurse and the professional medical staff will arrange cord blood banking with you.

Dedicated Transportation Team

After baby was born and cord blood is collected, client should call CRYOLIFE 24-hour hotline at 2110 2121. We will send our dedicated transport staff to pick up the BB box.

We promise to arrive at the hospital for BB box pick up within 12 hours after instruction from customers. (24 hours for Macau customers.)

Processing & Storage

Best in Class Technologies

AXPIn 2008, CRYOLIFE was the first in Hong Kong to migrate to automated processing with the adoption of the AXP Autoxpress™ Platform which achieved a higher recovery rate than manual processing. With the control rate freezing and MVE vapor phase liquid nitrogen storage tanks, we provide the best in class technologies in the market.

AXP Processing Bag Set lot no. is now marked on your Test and Storage Report

Since then, CRYOLIFE process cord blood sample with AXP processing system. We promises “What you paid is what you get”!CRYOLIFE will NOT just claim to use AXP but process manually in behind. To guarantee our service commitment, AXP Processing Bag Set lot no. is now marked on the test and storage report. Clients can understand what they pay for.

Using the cord blood / cord

CRYOshipper is a professional container dedicated to cryopreserved stem cell products transport. It ensures the cryopreserved unit will be kept at 150℃ for as long as 60 hours in transportation. The transport process will be monitored by an electronic device.

CRYOshipper has conformed with the Code of Federal Regulation (CFR) and is suitable for cord blood sample delivery. It has also passed IATA and able to be couriered by air.

To be well prepared of the life saving mission, our laboratory team conducts regular rehearsal for preparation of delivery by CRYOshipper.

Umbilical Cord Blood Net Volume Report

Cord blood cell count is directly proportional to the volume of cord blood collected. The higher the cell count of cord blood, the more beneficial to the clinical application of cord blood stem cells.

The doctors listed follow paid extra effort in cord blood collection, which is crucial to a person's life. Let's give our big hand to them.

About CRYOLIFE

CRYOLIFE is the first Private Cord Blood Bank in Asia, established in 1996. We believe in the potential of stem cell therapy in the field of reparative and regenerative medicine, and encouraged by the proliferation of successful cord blood transplants in the US, we decided to introduce the concept of saving cord blood to the local community.  Our mission is to serve the community's needs in cord blood storage by providing the best-in-class cord blood collection, processing and storage services, and continuous improvement in cryopreservation technologies.
