Abstract
The accurate determination of the presence of a fluid in a container is determined by assessing the difference in various pressure readings relative to a threshold value. The method distinguishes between actual aspiration of a fluid and aspiration of a film that can otherwise lead one to believe that fluid has been aspirated when it has not. The method is particularly useful in clinical analyzers such as automated enzyme immunoassay devices.
