Neutrophils, lymphocytes and macrophage/ monocytes can be found in all types of body fluid differentials. Bronchial cells can be found only in bronchial washings and BAL specimens. Mesothelial cells are found only in serous body fluids including pleural fluid, peritoneal fluid, and pericardial fluid.
Select the specific cells listed below that can be found in all types of body fluid.
1 SD = 68.3%, 2 SD = 95.5%, 3 SD = 99.7
As defined by a Gaussian distribution curve, what percentage of values would be expected to fall within two standard deviations of the mean:
A clinical laboratory scientist or medical laboratory scientist (or medical technologist in older terminology) may serve as all of the following except:
Using the formula on the right,
Cells/µL = 370 x 100 / 18 x 0.1
Cells/µL = 37000 / 1.8
Cells/µL = 20556 or 2.06 x 104
A sample of cerebrospinal fluid is diluted 1:100; the standard 9 squares of a hemocytometer are counted on each side for a total of 18 large squares.
Side 1-- 186 nucleated cells counted
Side 2-- 184 nucleated cells counted
total nucleated cells = 370
Using the standard hemocytometer formula shown on the right, what is the nucleated cell count per microliter (µL)?
In DNA complementary base pairing, guanine and cytosine pair and adenine and thymine base pair. Remembering the phrase "G-CAT" helps one recollect correct pairing.
Which nitrogen base would bind with a guanine nucleotide in forming double-stranded DNA?
The term affinity refers to the strength of attraction between a single antigenic determinant and a corresponding antigen binding site. The term avidity refers to the total strength of the attraction between an antibody and a multivalent antigen. The reaction between an IgM molecule (which has 10 antigen binding sites), and a multivalent antigen is therefore much stronger than that of an IgG antibody (which has only 2 antigen binding sites).
Avidity is best described by which of the following statements:
First, the RBC indices must be calculated. The MCV ((Hct/RBC) x 10) = 71 fL. Since the reference range for the MCV is 80-100 fL, this anemia would be classified as microcytic. The MCH ((Hgb/RBC) x 10) = 19.3 pg. Since the reference range for the MCH is 27-33 pg, this would be considered hypochromic. Finally, the MCHC ((Hgb/Hct) X 100) = 27%. Since the normal range for the MCHC is 33%-36%, this would indicate hypochromia which correlates with the MCH findings. The correct answer is therefore microcytic, hypochromic anemia.
A patient is admitted to the emergency room with lethargy and pallor. The CBC results are as follows:
RBC = 4.1 x 1012/L
Hemoglobin = 7.9 g/cL
Hematocrit = 29%
How would you classify this anemia?
