[Histonet] Re: Mouse tail sectioning

[Ellen Liebenberg]

We routinely section mouse tail using a protocol similar to 
yours.  However, I leave the tissue in 70% alcohol overnight, or longer, 
before processing.  It seems necessary for good dehydration.  I also use 
Clearite instead of xylene.

>Hello all;
>
>We are about to have a JACHO inspection and a problem was brought to my 
>attention.  It involves using two identifiers on all laboratory specimens.
>
>The below paragraph is from JCAHO FAQ web site for laboratory compliance 
>with the National Patient Safety Goals.  This particular statement seems 
>to answer the question about use of only one identifying number on a 
>pathology or any lab specimen.  Please let me know your interpretation and 
>how your laboratories comply to it.  Currently we have only the case 
>number (hand written) on the blocks and only the case number (hand 
>written) on the slides until after staining at which point there are 
>printed labels put on them.
>
>Take note that this FAQ was updated in January, 2005.
>
>
>FAQ-We use a label for the initial patient sample that contains only one 
>unique identifier, a number, to identify laboratory specimens.  This 
>unique identifier can be traced to multiple patient identifiers. Does this 
>meet the intent of the goal?
>ANS-No. The intent is to use two separate identifiers on the specimen 
>label. Confidence in an accurate identification improves as the number of 
>identifiers increases, depending upon their uniqueness.  A single 
>identifier can be more easily misread, resulting in avoidable errors. Bar 
>coding that includes two or more person-specific identifiers (not room 
>number) will comply with this requirement. (New 1/18/05)
