Test Accuracy
In a study of subjects aged 18–68 years, the Volume Cup showed an
accuracy of 96% compared to a standard laboratory test.
In a separate clinical study of 239 subjects aged 20–49 years, the Trak
sperm concentration test showed the following accuracy compared to a
standard laboratory test: <15 M/mL (93.3%), 15–55 M/mL (82.4%),
>55 M/mL (95.5%).
Factors that may impact test accuracy include:
• Presence of white blood cells, most commonly occurring due to infection
or recent surgery.
• Abstaining for less than 2 days or greater than 7 days prior to collecting
a sample.
• Not collecting the full ejaculate in the Volume Cup, particularly the
first portion.
• Not swirling the cup sufficiently before adding sample to the Prop.
• Not adding enough sample to the Prop.
• Reading results at an angle or with inadequate overhead lighting.
