Odds and Ends
100
Normal range for this electrolyte that is the primary intracellular cation is 3.5-5.1 mmol/L
What is potassium
100
This and hemolysis are common causes of falsely elevated K+ values in a serum sample due to collection issues.
What is hemoconcentration due to fist pumping?
100
IV insulin will do this to a patient's potassium levels.
What is lower a patient's potassium.
100
Sodium
What is an extracellular cation?
100
Most commonly used test method for electrolyte analysis.
What is ISE?
200
This electrolytes is the major component of the osmotic strength of the plasma and it's normal range is 136-145 mmol/L.
What is sodium
200
Incorrectly drawing blood into this tube will cause a falsely low (incompatible with life) calcium result.
What is an EDTA (purple) tube?
200
This is the hormone that stimulates the kidney to retain sodium, increasing the bodies sodium levels.
What is Aldosterone?
200
Potassium
What is an intracellular cation?
200
Test method for osmolality.
What is freezing point depression?
300
This is the term used to describe an increased potassium level.
What is hyperkalemia?
300
Increased Lipids and Proteins can cause falsely decreases in this electrolyte's results if measured by Indirect ISE.
What is sodium?
300
These are the 2 main hormones that regulate the bodies calcium levels.
What is PTH and Calcitonin?
300
Chloride
What is an extracellular anion?
300
Causes of increased osmolality gap.
What is when body produces excess ketones or toxic ingestion of alcohol or ethylene glycol are present at significant concentrations (> 10 mOsm/kg)
400
These are the panic values for the biologically active form of calcium.
What are Low < 2 mg/dL High > 7 mg/dL
400
This calculation can be done to check for instrument errors in chemistry.
What is the anion gap? (Na + K) - (HCO3 + Cl) normal range 10-20
400
This electrolyte has an inverse relationship with calcium.
What is phosphorous?
400
Magnesium
What is an intracellular cation?
400
Quantitative analysis of this electrolyte in sweat is considered the diagnostic standard for Cystic Fibrosis.
What is Chloride?
500
This is the formula to calculate osmolality and the normal range?
What is Calculated osmolality = (1.86)(Na+) + (glucose/18) + (BUN/2.8)+9 Normal range Serum = 275-295 mOsm/kg Urine = 300-900 mOsm/kg Osmolal gap= 5-10 mOsm/kg
500
A hemolysed sample will cause falsely increased levels of potassium, phosphorous, and this electrolyte.
What is magnesium?
500
This hormone is released by the kidney and ultimately stimulates the pituatary gland to release ADH and the adrenal gland to release Aldosterone.
What is Renin?
500
Calcium
What is an extracellular cation?
500
This electrolyte is part of the major buffering system of the blood and helps to maintain a neutral blood pH.
What is bicarbonate?
