title: [Correct handling of serum separating gel tubes is of significance].
abstract: We review the construction, handling, advantages and drawbacks of serum separator tubes. A study is reported, which demonstrates that serum potassium measurements are less reliable when gel-barrier sampling tubes are used incorrectly. We give guidelines for correct use of such equipment.
