Summary

This pilot study tested a new, noninvasive breath test to see if it could identify pregnant women at risk for gestational diabetes. Twenty pregnant women provided breath samples after drinking a special sugar solution, and the results were compared to standard blood tests. The goal was to see if the breath test is feasible and accurate enough for future use.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
13C labelled glucose breath test
What this could lead to
If successful, this could lead to a simple, noninvasive breath test to screen for gestational diabetes risk, replacing or reducing the need for blood tests.
What could go wrong
This is a very small pilot study with only 20 participants, so results may not apply to all pregnant women. The breath test may not be accurate enough to replace standard blood tests.
