The Hong Kong Red Cross Blood Transfusion Service pointed out that the demand for blood has a tendency to outpace the supply, pushing blood banks to near critical levels.

It added the blood inventories have to be duly replenished to maintain a stable blood supply for clinical transfusion to patients in hospitals.

Most donor centers open on public holidays including the day after Mid-Autumn Festival and the National Day. The center has prepared seasonal fruits for blood donors who come forward to give blood during September 18 to 22 as a token of thanks.

All successful donations at a donor center or donation vehicle during this period will receive one Nanshui pear or one Shatian pomelo.

Anyone aged between 16 and 66 (donation is possible up to the age of 76 if predetermined conditions are met), weighs 41 kilograms or above and is in good health is eligible to give blood.

To prevent crowds from gathering and long waiting times at the donor centres, donors are advised to make appointments by calling the donor centers or via the "HK Blood" mobile app.
