Hello !!
I have to transcribe an analytical data received from a supplier .
Its result is: BQL .
Can I translate it as = 0 (ZERO) ?

Because my software does't accept letters but only digits

I wouldn't, but you may have no choice if you have to enter something into the software.  I can only assume you can define each acronym, you'll have to determine what your quality group wants here.  I think it might be better to actually enter the LOQ.  Then at least, although you are lying, you are at least, not lying to your benefit.  But even that puts the quality department in a difficult position.  If a dozen samples all come below LOQ, and you always call them at LOQ, you have some precision (maybe 100%) and accuracy that you don't really have.  But to call something zero, when it is above LOD, that's just lying.  Supervisors will have to decide what to do along those lines.

Thank you. If I wrote "0 <LOQ?"
I saw that I can put the letters and numbers in my LIMS... but not only letters

[Arkcon]

Oh, in that case, I'd put < LOQ, 0.05, or whatever number is the LOQ.  That's perfectly clear, and doesn't claim accuracy or precision that isn't there.
