Activated Charcoal and Lab Test Accuracy Study

This observational study is looking at how activated charcoal affects certain blood tests in healthy adults. Researchers want to see if taking a common dose of activated charcoal (Actidose Aqua) changes your serum osmolality (a measure of particles in your blood) and osmolal gap. They also want to find out if activated charcoal can cause a false positive result for ethylene glycol (a toxic chemical) when using a specific lab test. The study is enrolling 8 healthy adults who are at least 18 years old. Success would mean understanding if activated charcoal impacts these lab measurements. The current recruitment status is unclear.

Study design
This is an observational study with 8 healthy adult participants. It is not a randomized study.
What's involved
You would fast before the study, drink a dose of activated charcoal, and have several blood draws over 6 hours.
Compensation
Not stated in the trial record.
Follow-up
Blood measurements will be taken for 6 hours after you take the activated charcoal.
