Laboratories that have switched

Laboratory Testimonials

More and more laboratories have decided to STOP providing the Friedewald Calculated LDL and have converted to providing a measured LDL. Below are three Case Studies that show how and why three laboratories made the change.

TESTIMONIAL:

A Large Regional Hospital on the East Coast

How: By setting up two lipid panels. Panel 1 contained Cholesterol, HDL and Triglycerides but no calculated LDL results. Panel 2 contained Cholesterol, HDL, (measured) LDL, and Triglycerides.

"...we performed a study... we decided that the Friedewald calculation is inaccurate too often... we just feel the direct method provides the best information."

TESTIMONIAL:

Large City Hospital in metro New York

How: As soon as a direct measured LDL became available the laboratory replaced the Friedwald calculated LDL in their Lipid panel with a direct measured LDL. While this added to the cost of the Lipid panel, the laboratory was now able to offer a better test result.

"...we were actually surprised at how well this was received. The doctors knew that many of their (out)patients did not fast before the test."

TESTIMONIAL:

Medical Center in western USA

How: Pathologist met with ordering clinicians and reviewed inherent problems with calculated LDL. Lab discontinued offering calculated LDL, but does offer a direct LDL.

"...our Pathologist insisted we provide the direct, measured LDL. He said there was simply too much uncertainty with the calculated."
