The Andrology laboratory at the Sophiahemmet recently became the first such laboratory in Europe to be accredited in accordance with the ISO-standard 17025. This is the international standard for medical laboratories. The routine measures of the laboratory for the examination of sperm samples have received the quality stamp of this accreditation. The control has been carried out by SWEDAC (Board for accreditation and technical control) and the work to gain accreditation has been going on for three years. Chemical and microbiological laboratories have, amongst others previously gained accreditation.
