A Driver’s Guide to the DOT Physical Urine Dipstick Test.

Source: Interpretation of Bedside Urinalysis

This post was published in Life In the Fast Lane , a blog from a group of docs from down under (Australia/ New Zealand), and would serve well to answer many of the questions you may have during your DOT physical about the urine test.

How accurate is the urine dipstick test?   Remember, the main purpose of a urine dipstick test during the DOT physical is to assess specific gravity, protein, blood and sugar, and not for a urinary tract infection (UTI).  The urine dipstick test does have it’s limits, especially when evaluating for infection in the emergency room according to this post and the reference given.   However it is important to note, as stated by the authors that:

  • A totally negative dipstick test is associated with negative microscopy in 90-95% of cases (false negative rate 5-10%) [Reference 1]

If you are concerned about a UTI, because you are symptomatic or the dipstick is positive for blood, leukocyte esterase or nitrites, we can always send your urine out for a full urinalysis.

Thanks guys and G’day mate!
