ACC Nutrition Module 7 Lab value significance

QuestionAnswer
What is or what is the significant of the lab value of Serum Proteins hemoglobin, albumin, transferrin, TIBC/total iron binding capacity, pre-albumin
What is or what is the significant of the lab value of Hemoglobin Low may indicate iron deficiency anemia, but not if blood loss is occurring or GI cancer
What is or what is the significant of the lab value of Albumin Has half-life of 18-20 days. Low indicates prolonged protein depletion, but can also indicate altered liver function, hydration status, and open wounds/burns
What is or what is the significant of the lab value of Transferrin The protein that binds to iron (low when there isn’t enough protein in diet, protein loss, or iron deficiency anemia)
What is or what is the significant of the lab value of TIBC The amount of iron in the blood for transferrin to bind on (an increase=iron deficiency, a decrease=anemia from other cause)
What is it or what is the significant of the lab value of Pre-Albumin Most responsive protein to rapid changes (the gold standard of assessment for possible protein malnutrition) Normal levels= 15-35, levels below 15 indicate at risk, and levels below 11 indicate need for aggressive nutritional intervention
What is it or what is the significant of the lab value of Iron deficiency anemia Decrease in storage iron. Anemia refers to a drop in hemoglobin. It takes several weeks after iron stores are depleted for anemia to develop.
S/S of anemia= *Tiredness, heart palpitations, sob, dizziness, chest pain *Foods high in iron: red meat, liver, eggs, green leafy vegs. like spinach, collards, raisins, molasses, whole grain breads
Urinary tests consists of what urea & creatinine, nitrogen balance
what is a urea test and the significance of the lab values Urea is the end product of protein (amino acid) metabolism, the rate of production in liver, and the rate removed from the kidneys.
What is it or what is the significant of the lab value of Nitrogen Balance Determined by comparing the nitrogen intake (grams of protein) to the nitrogen output over a 24 hour period •Positive balance: Intake greater>output •Negative balance: Output greater>intake
