4- Urinalysis Flashcards
What is the ‘typical’ value of USG in healthy dogs & Cats?
Dogs 1.015-1.045
Cats 1.035-1.065
T/F pH is influenced by diet
True
What is the ultra filtrate?
Protein-free filtrate of the blood
RBCs & proteins do not pass through a healthy kidney
T/F small proteins are filtered in a healthy kidney
True
T/F No amino acids are reabsorbed by tubules
False- almost all are reabsorbed
Describe the 3 different type of proteinuria
Pre-glomerular= High conc of protein into the filtrate- too high to be reabsorbed
Glomerular = Basement membrane barrier has failed due to inflammation, immune attack
Tubular = Damaged tubular cells are not able to resorb filtrate protein
Which proteinuria will cause nephrotic syndrome- and what is nephrotic syndrome
Glomerular proteinuria
= proteinuria in urine and hypoalbuminemia in blood
Which tests are not reliable in dogs and cats on a urine dip stick
Urobilinogen
USG
Nitrates
What crystal is seen in normal horses urine?
Calcium carbonate
what does the pH of urine generally reflect
the body acid-base status
in a animal with healthy renal function what does azotaemia ( concentrated USG >1.025) indicate
poor renal perfusion - due to dehydration/ hypovolaemia
