Protein, blood, or sugar in the urine at the exam — what it triggers

EXAMINER'S CALL

The $49 Medical Card Kit — $49, one-time payment

The checker reads your verdict. The Kit gets you through the exam: documentation packets for your condition, the two 45-day form clocks run as a calendar, the official medication form packet, waiting-period calendars, failure recovery, and the examiner phone script.

What the federal text says

The urinalysis at a DOT physical is a screening dipstick for protein, blood, and sugar (plus specific gravity) — it is part of the medical examination, and it is not the DOT drug test (different regime entirely; see the clarifier page). Abnormal findings do not carry published pass/fail numbers; they trigger the examiner's follow-up judgment: sugar points toward the diabetes analysis, protein or blood toward kidney and urinary evaluation, and the examiner may certify short, defer, or require documentation depending on the whole picture.

What that means for you

A flagged dipstick is a question, not a verdict. The drivers who handle it best arrive with the follow-up already done — recent labs from their own clinician — instead of waiting to be sent for it.

What moves the outcome

If you know a finding is coming (diabetics especially), bring recent lab work from your own clinician addressing it. If the examiner defers you for follow-up, the second-chance page lays out the sequence.

Which mode is this?

This question is NOT decided by federal text — the text leaves it to the examiner's judgment. Any site that prints you a pass or a fail here is inventing law. What moves this outcome is documentation, and that is what this page gives you.

Only a certified medical examiner on the National Registry can certify you. FreightVerdict reads the published federal standards — it does not certify, diagnose, or treat, and nothing here is medical advice.
