One tiny vial of blood contains a remarkable amount of genetic information about both the person from whom it was drawn and infectious agents like HIV circulating at the time of the needle prick. Because HIV mutates so quickly, having access to lots of samples to study is a valuable resource.
“It’s a diamond for science,” said Sikhulile Moyo, Laboratory Manager at the Botswana Harvard AIDS Institute Partnership (BHP). He was referring to the blood samples banked in the BHP freezers. “Specimens would be a more accurate term,” he corrected, “biological samples freely given to be processed for diagnosis or disease monitoring.”
