HA NOI — Blood type identification cards are commonly used in many countries but still a new concept in Viet Nam, said Nguyen Anh Tri, director of the Viet Nam National Institute of Haematology and Blood Transfusion (NIHBT) at a seminar in Ha Noi on Tuesday.
Widely used in Denmark, Germany and the United States, individual blood type identification cards could be an essential tool in managing blood resources and organising blood donations, said Tri.
The cards could ensure safer blood transfusions and increase the quality of healthcare services. Additionally, they could be used for personal identification, and would be a very helpful tool in emergency blood transfusions or blood donations, he said.
The cards were first introduced in the country more than one year ago by the Thai Duong Health Solutions Company, in co-ordination with the NIHBT.
So far about 20,000 Vietnamese people have a blood identification card, according to Nguyen Dang Quang, deputy director of the company.
The cards are sold at medical clinics that organise annual health checks for employees of companies and offices at VND80,000 (US$3.8) each.
The cards include four small circles with reagents in each circle. 10 microlitres of water and 10 microlitres of blood dropped into each circle and mixed together could tell people reliable blood test results after two minutes, said Quang.
The results can remain for two years when stored at 37 degree Celsius.
Besides help with blood transfusions, Quang said that the cards could also be used in developing different nutrition systems that address the needs of each person's individualised blood type.
People who are blood type B, for example, should have foods such as milk, fish, rabbit and sheep, whereas people who are AB blood type should have only a little meat and more vegetables.
Beef, chicken, cereals and vegetables are good for people with blood type O, while fish, goat meat, carrots and cabbage are good for people with A blood type.
The Thai Duong company, in co-ordination with the NIHBT and medical clinics across the country, will continue to introduce the cards to more Vietnamese.
They would also encourage companies and offices to buy the cards for their employees, he said.
