C. immitis is a dimorphic fungus which can be isolated from sputum specimens of infected individuals. When grown on Sabouraud's agar at 25o it grows as a mold with white aerial mycelium in about 3 to 5 days. C. immitis is known to produce arthroconidia which are "barrel-shaped" after 1 to 2 weeks of growth. Within three days at 28 ºC a sputum specimen placed on Sabouraud's dextrose agar with chloramphenicol and cycloheximide produced moist, grayish growth, with a white aerial mycelium, the organism is MOST likely:

The correct answer for this question is 1300 mg/dL. The laboratorian performed a 1:4 dilution by adding 0.25 mL (or 250 microliters) of patient sample to 750 microliters of diluent. This creates a total volume of 1000 microliters. So, the patient sample is 250 microliters of the 1000 microliter mixed sample, or a ratio of 1:4. Therefore, the result given by the chemistry analyzer must be multiplied by a dilution factor of 4. 325 mg/dL x 4 = 1300 mg/dL. After experiencing extreme fatigue and polyuria, a patient's basic metabolic panel is analyzed in the laboratory. The result of the glucose is too high for the instrument to read. The laboratorian performs a dilution using 0.25 mL of patient sample to 750 microliters of diluent. The result now reads 325 mg/dL. How should the techologist report this patient's glucose result? 

Public health guidelines recommend that manipulation of samples for influenza testing be done inside a safetycabinet. Safety goggles could be worn if the specimen or procedure may be prone to splashes or sprays ofinfectious material. Utility gloves are not necessary.Public health guidelines recommend that laboratory specimens for influenza testing must be manipulated usingwhich of the following safety precautions?

Triglyceride blood concentrations change significantly when you eat, as opposed to relatively stable levels of cholesterol, HDL, or LDL circulating in the blood. Whenever you eat a meal that contains fat, your triglyceride levels rise, which is why it is important to have a patient fast before the sample is collected. Which of the following lipid results would be expected to be FALSELY elevated on a serum specimen from a non-fasting patient?
