LATG 15 Diagnostic Flashcards
Diagnostic
fecal float
specimen is mixed with a solution of zinc sulfate, magnesium sulfate, or sugar in a centrifuge tube that is filled to the top with the solution. eggs float
Baermann method
Detects lungworm larve
PCR
detects types of organisms in skin scraping
hemagram
(CBC aka)
RBC
red blood cell count = total # rbc in specific volume of blood 10.2x10^6/ul
hematocrit
% of blood volume occupied by blood cells
PCV
packed cell volume in a hematocrit: rbc bottom
Buffy coat
WBC’s and platelets
Plasma
liquid (noncellular) portion of the unclotted blood.
WBC
white blood cell count
Platelet count
Thrombocytes for clotting
hemoglobin
oxygen-carrying component of red blood cells. grams/deciliter
White blood cell differential
Leukogram- % of WBC by type
Neutrophils
Heterophils (birds/reptiles)
45-75% of total WBC count
monocytes
3-5% total WBC count
Neutropenia
low levels of neutrophils
BAnd cells
Immature neutrophils/heterophils- no more than 1-3% total WBC count. ^ in bands signs of the beginnings of infection
Lymphocytes
leukocytes made by lymph noed 25-40%. ^ means infection or leukemia
eosinophils
red stained in cytoplasm. allergies or parasites
Basophils
inflammatory response
serum storage
-50 to-70c
myoglobinuria
excretion of myoglobin resulting from a traumatic muscle injury.
refractometer
specific gravity of urine: ^ gravity means dyhydrate v kidney disease
specific gravity
urine measures the relative solute concentration and is an indication of the kidney’s ability to concentrate or dilute urine
Fluorescence
imaging modality uses molecules that produce a certain light wavelength when exposed to ultraviolet light
Leukocytes generally make up what percentage of the total blood volume
1%

tank water
example of a contrast medium
gadolinium
During magnetic resonance imaging, which ions realign with the magnetic field
hydrogen
