HOW do you calculate %UBW actual wt/usual wt) x 100
How do you calculate BMI? lbs x 705// inches sq -->> This is the updated version
kg/meters sq ---> This is the standard version
How do you convert lbs to kgs? lbs/2.2 = kg
How do you convert inches to meters squared? inches/ 39.37, then square that number
Usefulness of the ALBUMIN test There is a lot of albumin in the body, and it is not broken
down quickly, so it is an indicator of prolonged protein depletion.
Normal = 3.5
Mild depletion = 2.8 - 3.4
Moderate depletion = 2.1 - 2.7
Severe depletion = < 2.1
, Usefulness of the TRANSFERRIN test More sensitive indicator of protein malnutrition than
albumin because it responds quickly to changes in protein intake. (Protein that transports Fe
from intestine to sites of Hb. Synthesis and breakdown).
High levels = Fe deficiency
Low levels = Fe storage is excessive (ex. liver disease, nephrotic syndrome (renal), burns).
Usefulness of the PREALBUMIN test Correlates with short-term changes in protein status
Has a short half-life that allows for a short-term and sensitive assessment of improving protein
status
Usefulness of the RETINOL-BINDING PROTEIN A sensitive plasma protein w a short half-life
Vitamin A status, liver and renal disease may affect test accuracy.
Usefulness of the CREATINE EXCRETION Creatine is a breakdown product of skeletal muscle
(formed from creatine).
As muscle atrophies during malnutrition, creatine excretion decreases (conserving)
Severe stress, fever and infection call all falsely evaluate Cr.
