Our repeat limits differ. If it is due to tissue falling off, we will try at
least 3 times
If it is due to unexpected, but within control, we will repeat it 2 times
Then if it is still problematic for the above 2, we will send out the block for
staining.
If it is due to technical error (wrong block, wrong stain) we will perform the
stain until correct, and it better not be more than once, LOL

Subject: [Histonet] REPEATS IN IHC
Hello, I was wondering if anyone in the histology laboratory (IHC) has a limit
on how many times one would repeat a stain; for example but not Limited too:
The tissue fell off, negative control, wrong block,etc.. for IHC DAB and/or
ISH. Thanks Ginny

Ginny:It seems you are asking for a "problem" average and that will vary per
laboratory and how the whole process is carried out.Section washed out from the
slide usually is consequence of poor processing or sectioning and has nothing
to do with IHC, although, perhaps, a wrongly performed HIER can cause it.Wrong
block is a mistake also having nothing to do with IHC and is always caused by
an inattentive HT not paying attention to the process.My point is that,
essentially, the lab should try to get to "0" mistakes and any one has to be
documented in the QC record but it will be interesting to find out the
"mistakes rate" you find and I think you should share it with all.Ren?
