classic infections that cause polyclonal gammopathy
erlichiosis, FIP
diagnosis of multiple myeloma
3/4 of monoclonal gammopathy, presence of lytic bone lesions, >20% plasma cells in bone marrow, bence-jones proteinuria (Ig light chains)
PP:F ratio
plasma protein to fibrinogen, differentiate between dehydration and inflammation bc fibrinogen moderate APP
which electrolytes are most important for ICF and ECF
ICF: K
ECF: Na
osmolal gap
measured- calculated, if increased presence of unmeasured solutes
corrected chloride
normal Na/measured Na x measured Cl
anion gap
+ - - (difference in unmeasured ions)
paradoxical aciduria
hypovolemia, hypochloremia, hypochloremia
when is compensation adequate
pH between 7.2-7.6
hepatic psuedofunction tests
albumin, BUN, glucose, cholesterol, vitamin K coags (synthesized in liver)
hepatic function tests
bilirubin, bile acids, ammonia
four components of nephrotic syndrome
hypoalbuminemia, proteinuria, hypercholesterolemia, edema
canine total T4 results
can only rule OUT hypothyroidism
canine free T4 results
need to use ED!! supports true hypothyroidism
canine TSH results
high TSH supports primary hypothyroidism
gold standard to diagnose hypothyroidism
TSH stim
what could cause total T4 to be highish in dogs with true hypothyroidism?
T4 autoantibodies
what tests would support feline hyperthyroidism besides total T4
free T4 by ED, but only in combo with total T4, gold standard is thyroid scintigraphy
what do the adrenal gland zones produce
GFR, salt, sugar, sex
best test for differentiation of PDH and adrenal tumor
endogenous ACTH
