The mean values (standard deviation (SD)) of the estimated sperm concentration as determined on the wet preparation, and the actual sperm concentration per Neubauer counting chamber
, are presented in Table 1.
Sperm viability by makler counting chamber
: Semen treated with taurine was measured the viability using Makler counting chamber
Some of its other features include a disposable counting chamber
, trypan blue viability, providing live images, estimating cell size, and saving date and cell images.
In addition, stained samples may be read on a Hausser counting chamber
at 40x magnification instead of 100x magnification because the natural cells enlarge more during RFTM incubation than in vitro cultured cells, stain characteristically and are easily observed under 40x magnification.
Pyuria: deposit in high-power microscopic field--WBC/ hpf--versus WBC/mm3 in counting chambers
The Auto M10 also uses the intuitive and user-friendly Cellometer software on a PC and works with the Cellometer disposable counting chamber

Total Leukocyte count (TLC) was done using Improved Neubauer's Counting chamber
Alternatively, manual chamber counting methods, which have been around for many years, can be used but come with a number of potential inherent sources of error (dilutional errors, dirty or broken pipettes, counting chamber
imperfections, and chamber filling errors).
Comparison with counting chamber
techniques, the "gold standard", is difficult because the latter techniques have several methodological steps that may contribute to imprecision and inaccuracy.
18,19] Alternative methods include enumeration of leukocytes using a counting chamber
, which has been found to correlate well with the leukocyte excretion rate.

It was determined that, because the targets were so low, any signal generated by a dirty flow cell, dirty optical, or dirty counting chamber
would appear in the monocyte count and weigh in on the results, thus producing a proficiency failure.
One hundred four CSF samples were examined for leukocytes in a paired comparison on the CD, the UF, and in a microscopic counting chamber
