Nutrition Labs Flashcards
Hemoglobin (Hgb) normal value
12-18 g/dL
Anemia definition
Lack of healthy red blood cells
BUN- blood urea nitrogen
Measure of nitrogen in the blood which comes from urea which is a byproduct of the breakdown of proteins into amino acids
Serum albumin
Measures the amount of albumin (a protein) in the clear liquid portion of the blood
Transferrin
An iron transporting protein
Increased BUN value
> 18 mg/dL
Starvation, high protein intake, sever dehydration, renal problems
Nutritionally, serum albumin measures…
Long-term nutritional status
Hemoglobin definition
Protein on red blood cells that binds oxygen for transport through the blood stream
Urine creatinine
Directly proportional to the body’s muscle mass.
Hematocrit (Hct) definition
Ration of plasma to RBCs after the sample is run through a centrifuge to separate the solid RBCs from the liquid plasma.
Urine creatinine normal range
0.4-1.5 mg/dL
Prealbumin measures…
Short-term nutritional status. Can detect daily changes in protein status.
Increased creatinine
> 1.5 mg/dL
Dehydration
Increased creatinine
> 1.5 mg/dL
Dehydration
Increased serum albumin
> 5.5 g/dL
Dehydration, shock, high protein diet
Normal BUN values
17-18 mg/dL
Decreased hematocrit can mean
Anemia
Decreased transferrin
Decreased serum albumin
Decreased creatinine
Increased hematocrit can mean
Dehydration
Decreased prealbumin
Normal hematocrit value
40-50%
Albumin
A protein made by the liver
Normal serum albumin
3.5 - 5.5 g/dL
Decreased hemoglobin (Hgb) means
Anemia
Urine creatinine normal range
0.4-1.5 mg/dL
Normal transferrin values
240-480 mg/dL
Urine creatinine
Directly proportional to the body’s muscle mass.
Decreased creatinine
Decreased BUN
Normal prealbumin (transthyretin) values
23-43 mg/dL
