protocol for 14-C triolein breath test

Last reviewed 01/2018

The protocol is as follows:

• the patient is fasted overnight
• collect a basal sample of expired air
• administer 10 microCi of 14C-triolein in a 60 g fat meal
• collect samples of expired air each hour for 7 hours
• measure the 14C in the expired air

Interpretation:

• the 14C activity in expired air is significantly reduced in patients with fat malabsorption
