Electrophoretic
– Technical Errors
UArtifacts
from hemolyzed specimens causes increases in:
-"2-globulin peak
-$-globulin peak
Upoor or
excessive migration due to:
-wrong amount of
time allowed for test to run
-wrong amount of
voltage applied
-wrong pH due to
bad buffer
Uexcessive
sample applied will cause:
-increased peaks
-cross
contamination of adjacent peaks
Uincreased
peak in $-globin area may
be due to:
-presence of
fibrinogen may be mistaken for increased IgA levels
