According to the Medicines and Healthcare products Regulatory Agency (MHRA) warning, the affected products are Becton Dickinson Diagnostics Vacutainer serum tubes.
There is a potential for a guard cap to come off, causing the spillage and potential exposure to blood.
The problem is caused because the outer diameter of affected lots have guard caps that are slightly larger than normal, says the warning.
If single use BD Vacutainers are used, the problem will not occur but the cap does not fit as tightly into reusable holders or ones not made by the manufacturer.
