The official word
Straight from TSA
“Diabetes testing supplies, including meters, lancets, and test strips, are allowed through the checkpoint. Declare insulin and other liquids for inspection.”
TSA / DOT (July 2026)
Before the checkpoint
Three calls that matter
No. Testing supplies are never confiscated. Lancets are fine when capped and packed with the meter.
Carry-on, with you. A delayed checked bag should never separate you from your glucose supplies.
Insulin and other liquid medications are exempt from the 3-1-1 limit when you declare them for separate screening.
