Doctors and the assessment of blood glucose testing sticks: does colour blindness matter?

摘要

A group of doctors with congenital colour vision deficiency (CCVD) were compared with a group of controls in their assessment of colour blocks in the colour range of a widely available blood glucose testing stick. The majority of doctors with CCVD agreed with controls on colour matching. However, subjects with severe CCVD tended to match test blocks to a wider range of options than either those with a less severe defect or controls. This paper discusses the implications of these findings.
