we’ll count blood cell elements

first instrument developed is

coulter (r) gen and LH series:

it’s a series

• generations of this instrument
• when they developed it the first time, they developed one, and then added on it eventually (improved it)
  • last edition of the instrument is the best

medical information must be updated each 5 years

• if you’re up to date, each 5 years you have to study again and check
  • if you don’t, you’ll be out of date

so how does it work?

blood;

when you take it, it should be taken on EDTA

usually, when you have blood in your hand

• we have to check
  • quality of the tube / blood
  • we have SOP:
    • we apply the SOP when receiving the sample
    • if the tube is good
      • blood is on EDTA
      • no clotting inside (macroscopically)

we take it, then place it in the nice machine
