What is the recommended action for drivers with a personal history of chronic kidney disease (CKD)?

For drivers with a personal history of chronic kidney disease (CKD), the recommended action is to obtain a creatinine and glomerular filtration rate (Cr/GFR) assessment. This test is crucial as it helps in evaluating kidney function and determining the extent of chronic kidney disease. Understanding the kidneys' filtration capacity is essential for assessing whether a driver is fit for duty.

Measuring creatinine levels and GFR provides critical information regarding the severity of kidney impairment, which can significantly impact a person's ability to safely operate a commercial vehicle. By conducting this assessment, medical examiners can make informed decisions about the driver's medical certification status and whether any further actions are necessary to ensure safety on the road.

This approach prioritizes the health and safety of the driver and others on the road by ensuring that any renal deficiencies are properly evaluated and managed, thus allowing for appropriate recommendations regarding fitness for duty.
