Cheap blood test helps HIV positive

(DrEddyClinic News) A Thai scientist has created what he says is a reliable and cost-effective method for counting white blood cells among HIV-positive people, using chicken blood.

The development is being hailed for its potential to save hundreds of millions of baht each year and improve medical treatment for people with HIV/Aids.

Kovit Pattanapanyasat, of Siriraj Hospital's faculty of medicine, who developed the test, replaced the microbeads usually imported for monitoring white blood cell (CD4) and T-cell counts in HIV-positive people with chicken blood.

Measuring CD4 and T-cells in the blood helps monitor the development of HIV in patients and how well anti-retroviral treatments are working.

Two standard methods for measuring CD4 and T-cell counts exist based on dual-platform and single-platform flow cytometry.

The single-platform system provides a more accurate result but is more expensive than the dual-platform method, which costs about 500 baht a test.

Each single-platform test needs to use imported plastic microbeads, which cost from 150 to 180 baht each.

Mr Kovit developed "biobeads" by using the chemical preservative glutaraldehyde on chicken red blood cells.

The biobeads can deliver results as accurate as microbeads when used with the standard single-platform method test, he said.

His biobeads cost from five to 10 baht a sample. About 10cc of chicken blood is enough to make biobeads for up to 1 million tests, he said.

His project was written up in the Journal of Acquired Immune Deficiency Syndrome earlier this year.

Mr Kovit's two-year study was funded by the Office of the Higher Education Commission and the National Health Security Office.

"This scientific innovation not only helps reduce the inaccuracy of CD4 blood cell counts commonly associated with the dual-platform method widely used in developing countries including Thailand but it may also help reduce health care costs," Mr Kovit said.

He said he is in the process of developing his tests for use by state laboratories providing CD4 and T-cell tests nationwide.
