Hemocytometer | calculation made easy

This video is about hemocytometer calculation, for RBC count, WBC count etc

The hemocytometer (or haemocytometer) is a counting-chamber device originally designed and usually used for counting blood cells.

The hemocytometer was invented by Louis-Charles Malassez. Cell counting proceture using hemocytometer, consists of a thick glass microscope slide with a rectangular indentation that creates a chamber. This chamber is engraved with a laser-etched grid of perpendicular lines. The device is carefully crafted so that the area bounded by the lines is known, and the depth of the chamber is also known. By observing a defined area of the grid, it is therefore possible to count the number of cells or particles in a specific volume of fluid, and thereby calculate the concentration of cells in the fluid overall.

The most perfect teacher 🙏🙏💙 thanks a lot .. really clear !

In 3:56 I saw you calculated the No. of RBCs/mL = 2.1x10^7. However, normally, a healthy people has 4-6x10^9 RBCs/mL. So is that any abnormal here?

Hema cytometer & petrof haussenchamber...Are they the same

[monicagalvez]

Can you do another take on the last part??? This calculation is so confusing.

But how does one account for the initial dilution of the blood in the first place?

[bhavyasonal]

Thank you for such a nice explanation ❤

[anjalisharma]

Ma'am how to collect cell and put it in a flask..I mean how can I measure it? I have to put it into flask and use these cells for some biochemical work

[hooos]

How about the dilution ratio? What if the the dilution ratio changes?

[rimshawaqar]

It is 2.05^10^7 and not 2.1^10^7 and you count 18 cells but these are 19.

Best video for petroff chamber ever...😁😁😁😁

[cyaml]

Almost understanding but partially there! Thank you.

[anxiousduck]

Thank you SO much for explaining. I'm using a resource that does not explain how the volume is known and it is absurd.

[manojkumarrinku]

But RBC count 1-5-13-21-25 five number box me karte hai

[ivo]

Spetacular! Thank you. I finally understand now.

When I attend a Diwali Festival in the UK I DO NOT call it "Divali".
Can you be just as courteous with your English? V and W are opposite pronounciations in English and all Indian Languages. It is unintelligible to a person who has English as a First Language.

How do the 9, 000, 000 people on the subcontinent cope who also have English as a First language?

What is this fake accent bro. So annoying
