15.8.1 - Foam in column
A layer of air bubbles that is concentrated on top of the blood column does not
affect the sedimentation process itself. The sedimentation develops normally
below the bubbles. However, too many bubbles bring about a shortening of the
effective blood column, which is a deviation from the Westergren method.
A layer of bubbles up to 5 mm: No message. Normal ESR result is reported.
A layer of bubbles from 5 to 25 mm: ESR warning 6: "Bubbles on top". Results
should be reviewed before release.
A layer of bubbles larger than 25 mm: ESR Error 3: "Too many borders found".
No ESR result is given.
