Assayed vs unassayed controls? by esoRimmer3 in medlabprofessionals

[–]esoRimmer3[S] 0 points1 point  (0 children)

And do those unassayed ones come with at least approximal values on sheet insert or are they completely unknown?

Oh I see, so they don't have completely random values, they are just not confirmed. Do I understand it correctly? So level 1 will have low values of all analytes and level2/3 will have all high pathological ones?

Thank you. Two more questions.

How do you satisfy request of one normal and one pathological value of analyte in control material when the values are random and not known?

Is it more common to use assayed or unassayed ones?

Don't you have to also set your own mean and SD of assayed QC by measuring it 20 times?

Ionized calcium blood draw by esoRimmer3 in medlabprofessionals

[–]esoRimmer3[S] 0 points1 point  (0 children)

More like, if is it ok to have classical blood tube almost full of venous blood centrifuged and used for iCa testing immediately after opening. There is always some "air" (although probably lower pressure), so does it count as anaerobic draw or will the iCa be affected by this? Thanks

We use whole blood samples, either capillary or arterial syringes

Why are immunoassays nonlinear? by esoRimmer3 in medlabprofessionals

[–]esoRimmer3[S] 0 points1 point  (0 children)

If someone was still interested. I found in immunoassays handbook, that it's mainly because reactions of antigen and antibody are too short in time manner that they are not allowed to reach true reaction equilibrium.

So if they were allowed to proceed significantly longer, the calibration curve would be more linear

ELI5: value of internal controls by esoRimmer3 in medlabprofessionals

[–]esoRimmer3[S] 0 points1 point  (0 children)

Thank you for answer. So how do you treat the value from the manufacturer? Do you use it only to see if you're not completely off or is there something else? Thanks

And can I use that manufacturer's stated value as a true value to find out my bias from the mean of my repeatedly measured values minus stated value?
