Optimal Utilization of Laboratory Testing

Overused/Misused Tests — Opinion

Slide 19

November 2011

Here's another example or overused or misused tests. These are in my opinion and based on the work that I have done with Dr. Fred Plapp who has developed some wonderful algorithms in the Kansas City area. Many sed rates, most uses of CKMB in the USA, most requests for ova and parasites, any low volume tests, especially if you are running more quality control samples than patient samples and large chemistry panels except for Medicare approved panels. Occasionally, you may hear a request from some of your doctors for a SMAC 20. Those are obsolete. Routine ordering of electrolytes, you think about that, if the patient is not on anti hypertensive medications there would be no reason to be checking electolytes in most outpatients. This is simply habit. Routine use of the CBC with differential instead of a CBC and routine use of rapid strep antigen test and throat culture if your physician intends to treat the patient regardless of the results and any other time when your tests add no value in this particular situation.
