Turn the system
OFF
when not in use for an extended period of time.
When running Postvasectomy tests do not interrupt test cycle nor interfere with system
or testing capillary in any way – this test is highly sensitive to any motion and requires
complete stability of the system during the 5-minute testing cycle.
Variations in ambient temperature can affect semen sample parameters.
It is essential
that semen samples are not heated
for testing. The SQA-Vision is calibrated to conduct
tests at room temperature: 20-25ºC (68-77ºF).
Semen is considered a biologically hazardous material and is subject to
individual laboratory protocols for handling such materials and at a minimum:
Laboratory coat, mask and gloves for operating personnel protection
Samples handling and waste disposal in specially marked hazardous waste containers
Only personnel trained to work with biologically hazardous materials such as semen
should be testing and handling semen
Operating Temperature and Humidity
Maximum operational humidity is up to 80% for temperatures of up to 31
º
C with
decreasing linearly to 50% at 38
º
C.
Operates in a wide range of ambient temperatures (15-38
º
C) however the system is
calibrated
to
measure
semen
samples
at
room
temperature:
20-25
º
C (68-77
º
F). Note: Extreme ambient temperature may impact the accuracy of
motility test results because of the known effect of temperature on human semen.
Operational Environmental conditions:
System is intended for indoor use at a maximum altitude of 2000m, mains supply
fluctuations ±10%, Overvoltage Category II, Pollution Degree II.
PC / Hardware
PC and device:
"All in One" - computer with SQA-Vision software and device.
Quality Control
Internal:
Electronic Self-Test and Auto-Calibration. Runs automatically upon start-up.
Besides that, reference values are verified prior to each test.
External:
Runs QC samples daily prior to testing or per laboratory protocol. Runs assayed
latex bead control:
"QwikCheck™-beads
" (product of Medical Electronic Systems) for
concentration and negative control for motility/concentration OR non-assayed: Latex
beads or stabilized sperm CAP or NEQAS for concentration.
Sample Testing
Sample Testing Temperature:
Calibrated for room temperature only. Motility results
will be impacted by heating the specimen (not recommended).
System calibrated to test Human semen and specified Control samples only.
Not
for use with animal semen.
SQA-Vision measurement capillary:
Disposable, plastic, testing capillary. Requires
500 µl of sample for normal volume testing, 20 µl for low volume testing, 300 µl for diluted
mode. Use only manufacturers’ certified testing capillaries in the automated system.
Field of View Stage:
This stage is an integral part of the SQA-Vision visualization
compartment. Vision™ fixed cover slip slides (obligatory for accurate test results when
manual sperm counting is required), standard slides (for debris scans and image
capturing) are accepted in the field of view stage using the supplied slide holder.
