A cardiovascular risk marker is an analyte in a body fluid that can be measured by the clinical laboratory and has been associated with the development of cardiovascular disease. Examples of risk markers include: LDL-C, triglycerides, and hs-CRP.
A cardiovascular risk factor is a condition (not a laboratory analyte) that is associated with an increased risk of developing cardiovascular disease. Examples of risk factors include: smoking, obesity, diabetes and hypertension.
Determine if each of the following is a cardiovascular risk marker or a cardiovascular risk factor.
1. Smoking
2. Obesity
3. Low density lipoprotein (LDL)
4. Hypertension
5. Triglycerides
6. High sensitivity-C-reactive protein (hsCRP)
IgE levels are often increased in patients with allergic disease. IgE binds to the membranes of mast cells and basophils, and if specific antigen is present to react with the IgE molecule, degranulation of these cells occurs, releasing histamines, and other substances into the blood or tissues.
Which of the following immunoglobulin classes is chiefly responsible for the degranulation of mast cells and basophils:
Each of the drugs/drug classes listed above have been known to cause drug-induced hemolytic anemia, although cephalosporins are the MOST COMMON cause. Cephalosporins can cause drug-induced hemolytic anemia when a patient produces antibodies to the particular cephalosporin drug in the presence of red blood cells. The drugs can alter the membrane appearance of the red blood cells, causing the body to mistake them as foreign. Complement becomes activated due to these antibodies; red cells are then destroyed causing hemolytic anemia. Dark urine, caused by intravascular hemolysis, is one of the most common symptoms associated with this condition.
Which one of the following drugs/drug classes is the MOST COMMON cause of drug-induced hemolytic anemia?
First, determine the number of WBC's from the hemocytometer as follows:
WBC count = (dilution ratio x # of cells counted x 10) / (# mm2 area counted)
Then: WBC count = (20 x 100 x 10) / (8) = 2500 WBC/mm3 (or 2500 WBC/uL or 2.5 x 103 WBC/uL)
Next, to find the WBC count per liter, multiply the WBC count/uL by the number of uL/L (there are 106 uL/L)
So: (2.5 x 103 WBC/uL) x (106 uL/L) = 2.5 x 109 WBC/L
Hematology
A 1:20 dilution is made for a manual WBC count. The four corner squares on both sides of a hemocytometer are counted. A TOTAL of 100 cells are counted in that area. What is the white blood cell count in terms of a liter (? x 10^9/L)?
A zone of inhibition is the area around an antibiotic-infused paper disk that does not show any bacterial growth. The antibiotic impregnated on the disk will diffuse into the agar in the area surrounding the disk. If the bacteria are sensitive to the antibiotic, they cannot grow near the disk. The size of the zone is proportional to how sensitive the organism is. If the organism is resistant to the antibiotic, it will grow very closely to the disk.
The size of the zone of suppressed growth on a sensitivity plate using sensitivity disks is referred to as the zone of:

hs-CRP is a more sensitive version of the C-reactive protein (CRP) test, a test that has been used for many years to assess inflammation in settings such as lupus, transplantation, infection, etc.
Which of the following cardiovascular risk markers is a more sensitive version of a test that is used to assess inflammation?
Blood plasma will contain coagulation proteins, but not in a clotted tube where serum is present.
Blood serum contains each of the following substances except:
CD34, a cell surface marker, presents on undifferentiated pluripotential hemopoietic stem cells. CD34 is a cell surface glycoprotein and functions as a cell-cell adhesion factor.
