[Histonet] RE: Idea for a new recycler

If formalin, xylene, hemo-de, Formula 83 and alcohol were all collected as
one waste stream, no recycler could separate this waste into recycled
formalin, recycled solvent (xylene/hemo-de/F83), and recycled alcohol all in
one run due in part to the small range of boiling points and in part to the
azeotropes formed between the various chemicals. In this particular
scenario, the alcohol and the formalin would distill over together along
with any water in the formalin, and there would be a considerable amount
solvent in the alcohol making it contaminated and not of any use in the lab.
If you have any questions, please contact us off site and we'll be happy to
assist you.

The Clo test is a clinical lab test. You need to go to that part of the
CPT coding book (sorry I don't have it available). 88300 is an anatomic
code (gross only, ie, it requires examination of a piece of tissue or
foreign body) and is entirely inappropriate for this test.

Hi everyone,
I am looking to see what CPT code everyone is using for reading Clo
Tests in the pathology department. I have heard of using 87081 but I am
not sure if this is accurate as this is for culture and the CLO is
biochemical reaction not a culture. Currently I have been using 88300
gross only.
Any help would be appreciated.
Thank you,
Amy Farnan

Some manufacturer should find a way where you can add all of the
chemicals together in one container and when the recycler runs it spits
out formalin in one, xylene/hemo-de/f83/ in another and alcohol in
another all from one run.
To opine on another histnet query from earlier
I think both have their place. I use CBG for xylene, form, hemo de and
alcohol using the hemo on the processor and depar, alcohol on processor
for low grade alc, and xyle for all but the last xylen on the stainer
using frsh for that. Creative waste is good and simple but the only
thing is mixing old and new formalin can't be good long term. What I
was thinking about doing was using creative waste gravimetric for the
first run, and then after that use the CBG to redistill NBF for round 2,
3, 4 etc. Hey where am I getting all this money and space? Still like
BR recycler too, just do not have one anymore, but liked it. All
recycling is good as long as people know which ones to use. Still seems
to be an issue for some people. I worked in a place where the techs
thought you could throw everyting in one container and the rcycler would
spit out clean alcohol, xylene and formalin from one collective run.
Hey manufactures?

Blake,
I think I put in my comments about Ventana's Vantage when you first posted
the question, but here goes again.. It is wonderful. Vantage is the best
thing to come along in my lifetime as a histo tech! Wonderful for patient
safety, easy for the techs to use and a manager's dream for all the data it

optimized workflow that reduces errors and significantly enhances patient
safety. It can be used stand alone, or integrated into an LIS / AP software
system.
Benefits:
* Flexible lab configuration for custom lab workflow
* Reduce errors and increase efficiency
* Just-in-time reporting of artifact locations or last know location
* Alerting for sub-process time violations and missing artifacts
* Deploy to Desktop PC's or mobile hand held's
* Configurable workflow
* Supports color selection for slide and cassette printers
I would be happy to set up an online WebEx demo of the system for anyone who
may be interested. Thank you!

I dabble in microscopy - well I say I dabble, my wife says otherwise! - and
I have a reasonably well equipped home lab, which includes the ubiquitous
Cambridge Rocker. I've had reasonably good results with plant tissue
sections but sharpening the blades has always proved to be a pain and I tend
to get mixed results. However, I've recently acquired a bunch of Accu Edge
low profile blades at very low cost but I'm unable to source a holder at an
affordable price. IS there anyone out there in professional histology land
who has for sale a used, even rough condition holder suitable for these
blades? You'd get the grateful thanks of both myself and my wife, who will
be more than pleased to see me spend less time muttering about my poor
sharpening skills!
Many thanks

Eva,
I would hold it in a buffer, i.e. Tris, PBS, etc. til you're ready to
stain. You might also refrigerate the slide in buffer if its going to

Eva,
If you dehydrate it again to 100% or xylene, it is less likelt to fall off

I was under the impression that B5, because of the mercury content, was

if there is a federal law regarding this? We no longer use B5, we use B+,
but I know someone in OK who is using B5 (I am in FL). Is he breaking any
laws by using it and/or should he be switched to an alternative like B+?

I'm looking at starting up a new histology lab and need everything, I have a
tight budget. Can anybody give me recommendations on where to buy
refurbished equipment.
Thanks

There has been a lot of discussion recently regarding recommendations for
formalin fixation of breast specimens. If you are interested in this topic
please read the following article published in the May 2010 issue of the
American Journal of Clinical Pathology by Ibarra JA, et al., "Fixation time
does not affect the expression of estrogen receptor".

One important thing to remember is that you should make sure All material
being used for validation is processed the same way. Will your control
tissue be purchased or processed in your lab? Control tissue is used for
validation but you should use tissue with various levels of positivity.

RE: [Histonet] Responses to IHC CAP
Validation question
If you are a brand new lab, how do you validate IHC if you are no= t
yet receiving patient specimens? Can the validation be done on cont
rol tissues only?

Any inspection that I have under= gone we have used the 25 to 30
case rule. Except for the Er/Pr//Her-2= . We use closer to 50
cases. We also use a TMA to make our live= s easier. The TMA
contains known positives and known negatives.
I= n cases of t-cell or b-cell markers or cytokeratins. 25 to 30
cases i= s easy. But when you are validated for more hard to find
markers (SV-= 40) then fewer cases is acceptable. We always throw
in a slide that w= e know will not stain for sv-40 like a tonsil -
then you can say it has spe= cificity.
Any inspector that I have come across is usually understanding= of
this. But I am sure that there are exceptions to this.........esp
ecially if they are not familiar with immunohistochemistry.

Subject: [Histonet] R= esponses to IHC CAP Validation question
The following is one respone= I rec'd:
1. I asked CAP who told me that they do not currentl= y have a
guideline on
validating but that they
recommend what is in t= he following book:
Quality Management In Anatomic Pathology, Promoting P= atient
Safety
Through Systems Improvement and Error
by Raouf E. Nakhl= eh, MD & Patrick Fitzgibbons, MD editors
sold by CAP !
Chapter 8-= Quality Management in IHC
That is what we follow.
I. Get a new antib= ody and optimize it with your positive control.
II. Once optimized you n= eed to run it on cases expected to be
positive
(how many?)
"a suffien= t size ..."
III. Must also be run on cases expected to be negative. (how= many?
IV. In a situation where you cannot expect a lot of cases or such
a
case has
never been presented in your lab, then you must say just = that.
(ex. some of the hormones we just use a pituitary)

Stain with cTnI and inspect for damage visually. Just a guess.
