Should pancreatic amylase be higher than total amylase?

: Ask the teachers: a patient twice urine test pancreatic amylase than the total amylase high normal?
: 1, testing principle: immunosuppression continuous monitoring method. Substrate 4,6-ethyl-a-D-malt heptosine-to-nitrophenol (EPS-G7) is cracked into a variety of fragments by α-amyloidase, and in the second reaction they are further hydrolyzed by a-glucosease to produce glucose and nitrophenol. Since salivary amyloid isoenzyme is selectively inhibited by two monoclonal
antibodies
complexes during the pre-incubation phase, the rate of increase in absorbentity is directly related to the vitality of pancreatic amylase in the sample.
2, the detection process note: residual saliva a-amylase vitality of up to 3%, very high salivary amylase vitality will make pancreatic amylase results high. Both saliva and skin contain a-amylase, so do not use your mouth to absorb
reagents
and avoid contact with the skin.
I have encountered before the ball
protein determination
value is greater than the
total protein
measurement value of the specimen (diagnosed as MM), I consulted the predecessor Chen Hongyu teacher, Chen Lao to the explanation is due to different measurement methods, different standards and caused differences (I am not very clear until now), perhaps yours is also the reason..
