CAP Checklist Item COM.10000

Many of our technical procedures refer to a vendor-provided manual for an instrument. This reference in our SOP also includes the version number of that vendor manual to be clear which version is being referred to in the event the vendor makes an revision.CAP checklist item COM.10000 requires that a complete procedure manual is available at the workbench and that all procedure manuals are document controlled. We have been cited by CAP for not placing these vendor-provided manuals under document control. Because there are several such manuals (many are hundreds of pages long) in place in any one lab, I'm curious to know how others are handling the document control of these vendor-provided instrument manuals. Help by responding online.

Is dilution correction required for urinary calcium measurement?

Generally, for calcium measurement it is recommended to add 20-30 mL of 6 mol/L HCL for 24 hour urine specimen or 1 to 2 mL for a random specimen to prevent calcium salt precipitation. However, It is not very clear from the literature whether we need to correct for the urinary dilution due to preservatives or not? Is anybody using any dilution correction approach? Really appreciate your thoughts. Share your ideas.

Clinically Acceptable Difference between Methods

I'm currently carrying out methods comparisons for Biochemistry and Hematology methods in our lab and I need to determine the clinically acceptable differences (bias) between the analyzers for each test parameter. Can anyone please put me through, or share any published data with me? Give your contribution online.
