| The reagent strip method for protein primarily tests for which type of protein? | View Page |
| Protein Error of Indicators Testing for protein is based on the phenomenon called the "Protein Error of Indicators" (ability of protein to alter the color of some acid-base indicators without altering the pH). In a solution void of protein, tetrabromphenol blue, buffered at a pH of 3, is yellow. However, in the presence of protein (albumin), the color changes to green, then blue, depending upon the concentration. This method is more sensitive to albumin than to globulin, detecting as little as 5 mg albumin/dL urine. Bence Jones protein and mucoprotein are examples of globulin components that are sometimes present in urine, but are not distinguishable by the dipstick method for protein. | View Page |
| Composition of Semen Semen is produced as a combination of secretions from the different regions of the male reproductive tract. Each fraction differs in chemical composition and function. The combination of these fractions during ejaculation results in the optimal environment for transporting sperm to the endocervical mucus in the female. Spermatozoa are produced in the testes. They mature in the epididymis. The testes also produce testosterone and inhibin.Fluid from the seminal vesicles accounts for approximately 70% of semen volume. The seminal vesicles are the source of fructose in semen. Fructose is used by the spermatozoa as an energy source.The prostate gland supplies about 20% of the volume of semen. Its fluids include acid phosphatase and proteolytic enzymes that lead to coagulation and subsequent liquefaction of semen. The prostate also contains most of the IgA found in semen.The bulbourethral gland produces mucoproteins that make up about 5% of the volume of semen. | View Page |
| Which of the following are characteristics of casts? | View Page |
| Cellular Casts Cellular casts consists of a Tamm-Horsfall mucoprotein matrix containing red or white blood cells, renal tubular epithelial cells, or a mixture of these cell types.
All cellular casts originate from the distal tubules. The presence of cellular casts is always abnormal. | View Page |
