SECTION I: Introduction
The SQA-Vision is a high-performance PC-based analytical medical device that combines
technology in optoelectronics, computer algorithms and video microscopy. The SQA-Vision
and
a fully integrated TOUCH-SCREEN work together to provide user friendly semen analysis testing.
Samples are run in the SQA-Vision testing device and all data entry and user interface is
computer based.
FRESH, POSTVASECTOMY, WASHED, SWIM-UP, DENSITY GRADIENT and FROZEN semen
samples as well as LONGEVITY testing can be performed on the SQA-Vision. Additionally MANUAL
testing can be performed utilizing the on-screen MANUAL COUNTER. The high resolution
visualization component of the SQA-Vision permits assessment of oligospermic specimens and
poor quality IVF samples.
When results fall below the automated dynamic range of the system, a LOW QUALITY COUNTER
opens automatically to permit manual sperm counting. Debris and round cell assessment is
performed using the DEBRIS/ROUND CELLS SCANNER. % Normal morphologically is assessed
automatically along with other semen parameters. Vitality and Morphology differentials can be
assessed manually using the enhanced visualization system and on-line counters.
The analysis time varies according to the type of sample being tested: Normal quality samples –
75 seconds; Low quality – 2 additional minutes; Post vasectomy – 5 minutes.
The system runs a self-test and auto-calibration upon start up. It also runs latex beads or
stabilized sperm external quality controls.
