|---|---|---|---|---|---|
| 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
🗑
