VLDL transports endogenous lipids, whereas chylomicrons transport exogenous (dietary) lipids. Cholesterol is transported by HDL and LDL.
The function of the very low density lipoproteins (VLDL) is to transport:
Patients who develop severe sepsis or septic shock commonly have increased plasma lactic acid values.

Match each of the descriptions with the appropriate magnification:
1. Color, Rouleau, Overall Slide Quality, Cell Distribution
2. Platelet estimates RBC-platelet-WBC morphology WBC differential RBC inclusions
3. Select area to examine, WBC estimate
Unconjugated bilirubin is a byproduct of RBC breakdown, or hemolysis. It would be expected to see an increase in unconjugated bilirubin when hemolysis is occuring at an increased rate. The liver enzymes would not remain at normal levels if there were a viral infection of the liver, chemical damage to the liver, or obstruction of bile ducts.
Chemistry
A patient presents with an elevation of unconjugated bilirubin, normal serum alkaline phosphatase, normal liver enzymes, and no bilirubin in the urine. This combination would suggest:

Which of the following disorders is characterized by increased production of chloride in sweat?
Multiple myeloma
Free T4 is affected the least by changes in plasma proteins during pregnancy.

Darkfield microscopy allows a lower limit of resolution than bright-field microscopy which helps the tiny spirochetes to be seen in patient samples. In darkfield microscpy, there is a dark background where directly transmitted light is excluded by a dark-field condenser allowing only scattered light to be focused on the specimen. With dark-field microscopy bacteria appear luminous against a dark background.
Which of the following microscopic techniques is best suited for direct examination of the infectious agent of syphilis?
1. B
2. D
3. A
4. C
Red to Brown Urine: porphobilinogen, hematuria, myoglobinuria, etc.

Match urine color with substance that might have been responsible:
1. Phosphates
2. Bilirubin
