title: [Difference of some laboratory findings between investigations in medical practice and the clinical laboratory].
abstract: Report about some spermatograms of a patient which were investigated in an andrological practice as well as in a clinical special department. There exist many differences especially concerning the sperm motility, sperm density and finally the autoagglutination of spermatozoa. It is not possible to explain these differences in detail, but it is to emphasize that a careful training of the technicians could be the best guarantee for successful work in a laboratory. Furthermore the intralaboratory control as well as the interlaboratory control should better be used.
