What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

Summary

This study explores whether a blood test can identify the bacteria causing a brain abscess, potentially avoiding the need for brain surgery to get a sample. Researchers will compare the germs found in the blood with those found in the abscess during surgery in 15 adults. If successful, this approach could make diagnosis safer and faster for patients who cannot undergo surgery.
