POC. 07520
Hello all!
I am doing my self-inspection for our CAP inspection next fall. My question is in regards to the following standard:
POC.07520
"If the laboratory performs test procedures for which control materials are not commercially available. there are written procedures for an alternative mechanism to detect immediate errors and monitor test system performance over time. The performance of alternative control procedures must be recorded."
Does this pertain to waived Hemoccult card testing since there are no commercial controls, only an internal control? Our ER physicians perform Hemoccult testing. The standard suggests testing specimen in duplicate or split-sample testing, etc. to verify test system performance. I know these physicians are not going to run the specimen again, so if this pertains, I am not sure what exactly to do. Any thoughts are greatly appreciated!
Thank you

Hemoccult is a waived test; analyzing the internal controls are sufficient. However, testing personnel must document that the internal controls are done. We use a QC log.
There are commercial QC as my physicians used to perform Hemoccult tape method. This is what they used to use:
Quantimetrix Dropper Urine Dipstick Controls - liquid, ready to use, store at refrigerator temperature (2-8°C)
until expiry date. Do Not freeze.
5 positive + 5 negative / pack.
1)
For Quality Control testing-
apply two drops of the control to one side of the tape. Wait 3 to 5 minutes.
2)
Turn the tape over.
3)
Apply two drops of Hemoccult Developer to the
reverse side of the tape, directly behind the QC.
4)
Read the results on the reverse side of the smear within 60 seconds.
Any trace of blue on or at the edge of the smear is a positive result.

Another FYI….the physicians don’t particularly want to perform QC….It was the Nurse Manager whom I also trained that ran the controls and did the proficiency testing (CAP).

Our policy states the following:
QUALITY CONTROL:
Two quality control mechanisms are used for this test:
External quality control is performed with each new lot and each new shipment. Internal quality control is performed with each test.
Internal Quality control is recorded on the Daily Log with each patient test run.
Hope this helps
