| Common clinical laboratory methods for the measurement of serum albumin are based on the properties of albumin as a/an: | Binding protein |
| If serum proteins were immersed in a buffer of pH 8.6, which protein, albumin (pI = 4.7) or gamma globulin (pI = 7.6) would migrate the farthest by electrophoresis, and toward which electrode? | Albumin/anode |
| The biuret method for total serum protein is used for serum but not for protein in urine or cerebrospinal fluid (CSF) because: | The method is not sufficiently sensitive for use with urine or CSF. |
| The acute phase reactant protein that also inhibits proteolysis and has the highest concentration within its globulin fraction is: | Alpha1-antitrypsin |
| A protein that is normally produced by the fetus but is found in increased amounts in the amniotic fluid in cases of spina bifida is: | Alpha1-fetoprotein |
| Of the following protein fractions, the one that is NOT produced in the liver is | Gamma globulin |
| Peptide bonds of proteins bind with _________ ions of biuret reagent to produce a colored product. | Cupric |
| Increased serum albumin concentrations are seen in which of the following conditions? | Dehydration |
| Portal cirrhosis is a chronic disease of the liver. Observed on an electrophoretic serum protein pattern, a predominant characteristic of this disease is: | A bridging effect between the beta and gamma bands |
| A glycoprotein that binds with hemoglobin to facilitate the removal of hemoglobin by the reticuloendothelial system is: | Haptoglobin |
