N = number of cells (sperm)
Area = 9 mm2
Average of cells = mean of cells on both sides of the chamber / 9 squares
Dilution = usually undiluted “0”
Depth = 0.1mm

Concentration cells/ml = average of cells x dilution x 1000(where is this from) / # squares

]]> Comment on Urine pH And Its Clinical Significance by Jean Stein https://laboratoryinfo.com/urine-ph-normal-levels-range-chart/#comment-332361 Sun, 03 Nov 2024 15:50:56 +0000 https://laboratoryinfo.com/?p=6832#comment-332361 Hello
Question 1: At home, when using a dipstick, can we just take the sample while urinating instead of putting the urine in a beaker and then dipping the diptick?
Question 2: If not, why?
Thank you,
Jean Stein

Literature recommends no dilution but doesn’t mention area to count.

]]> Comment on Manual Cell Counting With Neubauer Chamber by Diego Méndez https://laboratoryinfo.com/manual-cell-counting-neubauer-chamber/#comment-327045 Wed, 28 Aug 2024 13:52:30 +0000 https://laboratoryinfo.com/?p=871#comment-327045 In reply to asad.

It comes from the product of area, depth and dillution.
Area = 4
Depth = 1/10
Dillution = 1/20
1/20 × 1/10 × 4 = 4/200 =1/50
Considering that you are dividing cell count by 1/50 thats is equal to multiplying cell count by 50.
