Valproic Acid results do not
match another method. Why?
MULTIGENT Valproic Acid is an indirect
method, in which lower valproic acid
concentrations produce higher signal levels.
The reading wavelength of 604 nm minimizes
interference from HAMA (human anti-mouse
antibodies), hemolysis, bilirubin, and lipemia.
The disagreement between methods may be
due to cross reactivity and interference
differences.
Which controls are recommended? Which
controls have AEROSET assay values?
Bio-Rad Immunoassay Plus controls have
been used successfully with this method,
although system-specific assay values are not
provided in the package insert.
Why am I getting negative calibration rates?
Is this normal?
This is normal. The competitive binding
method provides a curve in which the signal
is inversely proportional to concentration,
i.e.
, low sample values produce the highest
rates. The zero calibrator rate (highest rate) is
used as a blank and is subtracted from the
rates of all other calibrators, causing them to
be negative.
