Sketch the O2-consumption curves obtained for the mitochondria in Nephelometry has largely replaced RID in most clinical laboratories as the preferred method for measuring intact immunoglobulins, immunoglobulin light chains, immunoglobulin heavylight chain pairs, and many other proteins in body fluids. The most important advantages of this method is the possibility to use plate readers connected to computers which enable automated reading; an error that occurs at a point of a wrong reading does not result in having to perform the whole analysis all over again. Now when we talk about disadvantages these advantages of this method now they does not take into account whether they are alive microorganisms there and allow you microorganisms they cannot distinguish and they doesn't take in account in two account and next must be very careful with the standard curve. Other authors a. transferase A spectrophotometer is used to determine turbidity ("cloudiness") by measuring the amount of light that passed through a suspension of cells. This can contribute, for example, to increasing microbial resistance, overloading the health system and decreasing the patient's quality of life, who will remain ill.
