Give this one a try later!

Definition
- Endogenous enzyme: reacts with an added substrate to yield a
fluorescent or UV absorbing product. Alkaline phosphatase (ALP) is
the enzyme used.
- Endogenous Substrate: an enzyme is add with a substrate and
this generates an electrochemical current (glucose oxidase) or
other
detectable product (H2O2)
- Activity: Measurement of reaction rate (units)Only the
active enzyme is measured
- Mass: Quantity of protein (moles or grams)Can be active and
inactive forms of proteins.

5.What is the role of monocytes and macrophages?
a.They are involved in the innate immune system response to protect
against infection
b.They are the largest blood cell
c.They are involved in control of clotting
d.They are involved in the adaptive immune response comprised of B and T
cells among others
Know EMIT is a homogenous immunoassay (slide 44) and how it works
(slides 42-43)
, Know what enzyme-based clinical assays can be used to measure both
endogenous enzyme and endogenous substrate. (slide 28) Activity
represents active enzyme and mass/amount represents total
(active+inactive) protein amount of enzymes. (slide 29)
3. For a Qualitative Test, sensitivity is determined by:
a.TP/(TP+FP) - the number of true positives divided by all positive results seen
by the test
b.TP/(TP+FN) - the number of true positives divided by all results that should
have been positive
