BACKGROUND
The QwikCheck™ Liquefaction kit manufactured by Medical Electronic Systems (MES) is used to accelerate the liquefaction of viscous or incompletely liquefied semen samples that remain viscous thirty minutes after collection.
The kit contains: 20 single dose, 5 mg vials of lyophilized α-Chymotrypsin and a product insert.
OVERVIEW
Recently the Chymotrypsin used in the kit has changed in the following ways:
1. New supplier
2. Chymotrypsin is now a thin powder (previously it was irregular crystalized particles).
3. Although the 5mg powder weight is exactly the same as the irregular crystalize particles of the previous Chymotrypsin, it can be seen to occupy a smaller volume in the individual single dose vials.
Notes:
• Clinical testing of the new Chymotrypsin vs. the old did not demonstrated any significant change or negatively impact semen parameters.
• The required amount of 5 mg of chymotrypsin per vial has not changed
• The product insert (instructions) has not changed.
