ABSTRACT:
A method and apparatus for controlling the processing of a liquid sample, e.g., a blood sample, based on a measurement related to the sample's ability to coat a surface against which the sample is brought into contact while being routinely transported. Preferably, the sample is advanced through a tube, and the amount of sample residue remaining within the tube is measured and correlated to coating process subsequently carried out on the sample, e.g., a process for producing blood-smears on a microscope slide. In a preferred embodiment, the amount of sample residue in a blood-transport tube is used to control the motion profile (i.e., acceleration and velocity) of a drop-spreading member used to spread a blood drop on a microscope slide in an automated slide-making instrument.
