Creatinine clearance tests are utilized to estimate the glomerular function of the kidney. The creatitine clearance calculation is defined as the volume of plasma that is cleared of creatinine by the kidney per unit of time and uses the following formula:
creatinine clearance = Urine creatinine conc x Volume / Plamsa creatinine conc
Creatinine clearance measurements have a recommended specimen requirement = 24-hour urine collection.
Which of the following tests would be useful in the assessment of glomerular filtration:
Malbranchia species share the production of alternate staining arthroconidia as a common feature with the mold form of Coccidioides immitis.
Both Geotrichum species and Trichosporon species produce rectangular-shaped arthroconidia; however, they are regularly rather than alternately staining. Additionally, the arthroconidia of Geotrichum may produce germ tubes from one corner and the arthroconidia of Trichosporon species may produce blastoconidia from adjacent corners, features not shared by either Malbranchia species or Coccidioides immitis.
The hyphae of Microsporum canis, as seen in direct KOH mounts of skin scales, may break up into arthroconidia; however, they are much narrower in dimension and do not share the alternate staining characteristics.
Microbiology
The hyaline saprobic fungus that has microscopic features similar to the mold form of Coccidioides immitis is:
In Rouleaux, red blood cells appear as stacked coins - formation occurs as the result of elevated globulins or fibrinogen.
The RBCs indicated by the arrows in this illustration are the result of:
Polyspecific antihuman globulin (AHG) reagent contains both anti-IgG and anti-C3d.
Polyspecific antihuman globulin (AHG) reagent used in antiglobulin testing should react with which one of the following?
