Understand Calibrator-Standard-Control with Example/ Clinical Lab

#Calibrator : fixed value, matrix is same as sample, available in liquid or lyophilized form
#Standard : fixed value, matrix is not same as sample
#Control : value in range, matrix is same as sample, available in liquid or lyophilized form
#calibration curve
#Quality control

Nice way to make students understand......keep it up....👍🏻

Thank you, Question: What are parameters as mentioned at 4:00?

Thank you very muchhhhh🎉🎉🎉

[@emadissawy7811]

please I hope you can explain the difference between standard and calibration And can you also explain what a blank is? But I hope you write the explanation in an easy and simple way Sorry to bother you

[@user-vg6xm6ub6u]

Blank is actually used to set the zero absorbance in the machine. For blank we can use Distill water or Reagent blank i.e reagent without sample For a particular test, reagent blank will be best to use. Thank You

@@user-vg6xm6ub6u What does it means if the blank failed?

Does the result using calibrator is more accurate than standard because it has the same matrix as the sample? For example why in urea test (berthelot) calibrator is used instead of standard ? It would be awesome if you help me with my question Thank you for your useful video

[@user-vg6xm6ub6u]

It is better to use calibrator instead of standard, but at the same time test such as urea which has wide reference value in which small fluctuation in result doesn't matter can use any of either std or calibrator

@@user-vg6xm6ub6u thank you for answering ! It meant a lot! I have another question about the urea test (berthelot) Why in kits of the test there are 2 different reagents and we have to mix it to make a working reagent? Why they don't make a prepared working reagent? Does NADH reaction with something and makes the reagent unusable? I'd be so happy if you could help me with this I'm sorry if I'm bothering you with my questions

@@user-ds4rm6tp9r It is to increase the stability of reagent, they should be stored isolated
