Michels Transport Media exp date
Glen, I have received renal biopies in Michels with an expired date on
media, and will run for immuno. Will it compromise the studies?
Not sure, some of the cases have been negative and some positive and some
contain no glomeruli, therefore no immuno has to be performed.
I do know that those vials received after expiration date, contain alot of
crystaline substance around the lid.
We do have to note on report that biopsy was received with an expired
transport media. Why would you want to compromise an important study?
Our "customers" frequently call us "We are performing a kidney biopsy, all
I have in the refrigerator is a vial of Michels Transport Media with an
expired date, what do I do??? (they are located in another city). Obviously
I inform them "gee, why did you wait so long to call" and then tellthem
lesser of two evils is to give neprologist the Michels vial, inform them
that is all you have, but you are requesting updated material.
If you are inspected by CAP, Glen, no expired fixatives, reagents can be in

Teresa & All,
I was wondering if Michels can be used safely if it is just after the
expiration date? I have almost a full bottle that will expire in a month.
It has been in the fridge for the duration and I don't believe that it would
compromise incoming skin or kidney bx.'s If someone has had problems with
expired Michels, please let me know.
Thanx in advance,
