EpiScreen Plus™

Neutral Alpha-Glucosidase determination

The bulk of the alpha-glucosidase activity in semen, and more particular that of its neutral iso-enzyme (NAG), depends on secretion by the epididymis.
In patients with azoospermia and normal androgen levels in peripheral blood, NAG activity in semen plasma is a reliable marker of the epididymal contribution to the ejaculate.

Low NAG activity in seminal plasma of patients with oligozoospermia may reflect partial obstruction of the epididymides, associated with infections or inflammatory disease2, 5. Enzyme activity in patients with normal sperm concentration is correlated with the result of the Shorr-stain of midpiece and tail, reflecting changes in cell membrane, induced by epididymal secretion. The EpiScreen Plus™ assay may assist in the diagnosis and the management of male infertility.

EpiScreen Plus™ has a 24 month shelf life from date of produce.

EpiScreen Plus™ has been CE marked according to the specifications set forth in the European Medical Device Directive 98/79/EC.
