Clin Path Review 7 Flashcards
Hyperkalemia is a life-threatening disorder assoc. w/what?
Acute renal failure and urethral obstructions
How is calcium affected by acute renal failure?
Normocalcemic
How is calcium affected as renal failure progresses?
Hypocalcemia
Hypocalcemia can secondarily cause what endocrine disorder?
Hyperparathyroidism
Hypercalcemia can be assoc. w/acute renal failure involving specific toxins such as what?
Grapes and raisings
What e-lyte abnormalities are ALWAYS a finding in uroabdomen?
HypoNa and hypoCl
Which dog breed is the poster child for familial glomerulonephropathy?
Wheaton Terriers
Mod/marked hypoalbuminemia, mod/marked protinuria, +/- evidence of renal insufficiency
Glomerulonephropathy
PLN that leads to abdominal effusion
Nephrotoxic syndrome
Acute onset of clinical signs, ammonia breath, good BCS, oliguric, seizures
Acute renal failure
Marked decrease in GFR leading to azotemia
Acute renal failure
Slow onset, poor BCS, PU, ammonia breath, depressed
Chronic renal failure
Abd effusion, hyperK, hypoNa, hypoCl
Uroabdomen
How does CREA dx a uroabdomen?
Effusion [CREA] is higher than serum [CREA]
What are solutes that will interfere and artificially increase TP?
CHUGL (cholesterol, hemolysis, urea, glucose, lipids)
Proportional PCV + TP decrease = ?
Blood loss
Proportional PCV + TP increase = ?
Dehydration
Probability a healthy patient tests negative
Specificity
The probability that a positive (abnormal) test result truly identifies disease in a patient
Positive predictive value
The probability that a negative (normal) test result truly identifies absence of a disease in a patient
Negative predictive value
[(TP)/(TP+FP)x100]
PPV
[(TN)/(TN+FN)x100]
NPV
Which tube has no anticoagulant and no additives?
Red top tube
Serum for a chemistry panel is obtained from what tube?
Red top tube
