The MCV is indicative of microcytosis with MCV=<80fL. The RDW is within normal limits and indicative of a homogenous cell population.
If the MCV was >100 fL, this would be indicative of macrocytosis. An RDW that was outside of normal limits would be indicative of a heterogenous cell population.
An 18 year old female has a CBC as part of a routine physical exam. The following results were obtained and the physician determines she is anemic. After reviewing her CBC results shown below, which of the following would be an appropriate description of the anemia?
White blood cells (WBC): 5.6 x 10^9/L (RR:4.0-10.0 x 10^9/L)
Red blood cells (RBC): 3.7 x 10^12/L (RR: 4.2-5.9 x 10^12/L)
Hemoglobin: 9.9 g/dL (RR:12-16 g/dL)
Hematocrit: 28% (RR: 37-48%)
MCV: 75 fL (80-100 fL)
RDW-CV: 14% (RR: 11.0-15.0%)

Serum ferritin is a good indicator of iron deficiency. However, it acts like an acute phase reactant, being elevated in a large number of conditions. Patients who have iron deficiency as well as another condition that elevates serum ferritin levels may therefore have normal or even elevated serum ferritin levels.
Which one of the following statements about serum ferritin are true:
Which one of the following statements about serum ferritin are true:

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:

Glucagon and epinephrine promote glycogenolysis, conversion of glycogen to glucose, which increases plasma glucose.
Cortisol along with glucagon increases gluconeogenesis, formation of glucose from noncarbohydrates which also raises plasma glucose concentration.
Chem
Which of the following hormones increases plasma glucose concentration by converting glycogen to glucose?
Please select all correct answers

Matching: The detection of a distinct odor is often helpful in the presumptive identification of bacterial culture isolates. Match each of the odors listed with its corresponding bacterial species name.
1. Streptococcus anginosus (milleri)
2. Pseudomonas aeruginosa
3. Eikenella corrodens
4. Alcaligenes faecalis

When making a platelet concentrate, the proper procedure is to start with a low centrifugation of the whole blood bag. After the plasma is removed, it is centrifuged again at a higher speed to separate the platelet portion from the plasma portion.
Blood bank

Hemolytic transfusion reactions seldom occur because the incidence of unexpected antibodies in random patients is relatively low, e.g., 3-5% is sometimes cited.
Being transfused with O Rh negative RBC is irrelvant if you have an unexpected antibody like anti-K or anti-c.
Incompatible red cells may "bleed out" but only if bleeding is brisk. Even then, a hemolytic reaction may occur later once the patient's antibody rebounds and destroys remaining antigen-positive donor red cells.
It's true that some patients have only cold-reactive antibodies that will not react at body temperature. But this does not explain why warm-reactive red cell antibodies cause few reactions Why do so few patients transfused with un-crossmatched red cells in an emergency experience a hemolytic transfusion reaction? Select the one best reason.
