Appendix 11: Concentration Standard: Counting Chambers
A number of commercially available counting chambers are used in laboratories for manually counting sperm
cells. These chambers vary by depth and one type requires a diluted sample. It has been clinically established
that counts vary by approximately 30% depending on the chamber used.
The SQA-V permits the user to select the type of chamber the laboratory has implemented as a standard for
manual semen analysis. Once the concentration standard (CONC. STANDARD) has been selected the SQA-V will
automatically run semen samples based on that standard.
SQA-V Set-Up:
Select SERVICE > SERVICE DATA.
Log into V-Sperm and go to
SET-UP > SQA-V > CONTINUE
Select a
CONC. (concentration) STANDARD
based on aligning the system with the options shown in
the table below:
CONC. STANDARD #1
CONC. STANDARD #2
Commercially available counting chambers are divided into two unique groups:
Standard #1:
10-20 micron depth and do not require sample dilution.
Standard #2:
100 micron depth (haemocytometers) that require sample dilution.
The table below classifies some commercially available chambers:
