Anticoagulants (clot inhibitors) Anticoagulants
Used
anticoagulants in the case of the use of samples of plasma or total
blood as required by the experiment and it must add an anti-coagulant to
a tube blood collection if withdrawn immediately and usually closes the
wall of a tube blood collection in anti coagulants, and it should be
noted that the choice of anticoagulant must be based on consideration that this counter will not affect the chemical analysis, and this point is very important. Because
the sources of anticoagulant compounds are chemical salts of some
metals such as sodium, potassium, lithium, so it can not be used
anticoagulants of sodium and potassium salts when the terms of the
analysis set electrolyte As sodium and potassium, because that will
cause a much more positive in the results of the analysis but in such a
case can be used anticoagulants for lithium or ammonium.
In
the case of analysis of calcium in the blood can not be used sodium
oxalate salt as this will remove all the content of the sample in the
form of calcium oxalate Sedimentation calcium.
As
well as working anticoagulants to inhibit the effectiveness of some
enzymes, such as the enzyme phosphatase Acid Acid Phosphatase and
phosphatase baseband Alkaline Phosphatase and the enzyme dehydrogenase
from lactate LDH The salts of fluoride of potassium or sodium Inhibit the
effectiveness of the enzyme urease, while operating effectiveness of
the enzyme amylase, can also anticoagulants lose the test pathological significance
