|
BMP (aka chem 7) contains...
|
-lytes
-BUN/Cr -glucose |
|
|
CMP =...
|
BMP + LFT
|
|
|
What are the 'lytes' that are tested?
|
-Na
-K -Cl -CO2 |
|
|
Cholesterol panel includes...
|
-TC
-LDL -HDL -TG |
|
|
TFT tests for...
|
-T3
-T4 -TSH |
|
|
What cardiac enzymes are tested?
|
-myoglobin
-CPK -troponin -MB fraction -LDH |
|
|
osmolality
|
-conc of solutes in solution
-use with lytes to assess the kidney function -high osmo stimulates ADH to cause for water reabs and dilute the particles |
|
|
Factors that can influence your chemistry results...
|
-hemolysis (effects K)
-timing (blood sugars, cortisol) -lab error (repeat the test) |
|
|
BUN
|
-end-product of protein metabolism, formed in the liver and excreted in the urine
-NL: 10-20 -use in conjunction with Cr |
|
|
Elevated BUN...
|
-azotemia
|
|
|
Dec'd BUN...
|
-liver disease
-fluid overload -malnutrition -early pregnancy -nephrotic syndrome |
|
|
prerenal azotemia
|
-Urea levels rise with hemorrhage, shock, trauma, sepsis, diets high in protein, increased protein catabolism (tumors), dehydration
|
|
|
postrenal azotemia
|
-urethral obstruction
|
|
|
SCr
|
-NL: 0.5-1.2
-depends on muscle mass -more stable than BUN (better reflection of kidney function) |
|
|
elevated SCr
|
-decreased renal function &/or renal blood flow, diabetic nephropathy, urinary tract obstruction, rhabdomyolysis, increased muscle mass
|
|
|
dec'd SCr
|
-loss of muscle mass
|
|
|
BUN/Cr ratio
|
-NL: 10:1
-If >15:1, look for prerenal causes -<10:1, look for liver disease, low protein diets, dialysis |
|
|
Na
|
-NL: 136-145
-critical values <120 or >160 -Major extracellular cation |
|
|
hyponatremia
|
-most common electrolyte disturbance in hospitalized patients
-Never replenish Na more than 12mEq/L/day |
|
|
hypovolemic hyponatremia
|
-n/v/d
-diuretics |
|
|
hypervolemic hyponatremia
|
-CHF, edema, ascites, IV fliuds
|
|
|
euvolemic hyponatremia
|
-SIADH
|
|
|
hypernatremia
|
-find thirst and hyper-reflexia
-Causes- inc. water losses, burns, diabetes insipidis, hyperaldosteronism, Cushing’s syndrome |
|
|
K
|
-NL: 3.5-5
-Predominant intracellular cation -Ace-inhibitors increase K+ |
|
|
hypokalemia
|
-alkalosis
|
