benzoylecgonine and Communicable-Diseases

Besides modern virus-screening methods, the avoidance of transfusion transmission of viral diseases is based on the best possible selection of healthy donors. Unfortunately, most of the relevant behavior-related risk factors are not accessible to objective verification. Drug screening can be used to validate a defined section of donor statements. It may be assumed that donors who conceal drug consumption may also conceal other relevant risk factors.. Hair and urine samples from 186 young potential donors who denied having consumed drugs were investigated by gas chromatography with mass selective detection and a urine fluorescence polarization immunoassay for cannabinoids, amphetamine and amphetamine derivatives, cocaine, and opiates.. Ten potential donors with 14 positive results on hair and urine analyses (6x cannabinoids, 4x cocaine, 1x opiates, 3x dihydrocodeine) could be identified in the population investigated.. The donor history is not adequate for identifying potential donors with risk factors. Deliberately false statements concerning risk factors are a clear breach of trust between the blood bank and potential donors. These unreliable donors represent an incalculable risk for the transfusion recipient. Therefore, it is appropriate to validate donor statements about drug consumption by random hair and urine analyses and to exclude from the donor pool all persons revealed as drug users.
