NTP NTP Functional Nutrition & Lab Testing 2 — Questions and Answers
Question 1: Which functional lab test is used to assess overall thyroid health beyond standard TSH, including conversion of T4 to T3?
- TSH only
- Full thyroid panel: TSH, free T4, free T3, reverse T3, and thyroid antibodies (Correct answer)
- Serum calcium
- Adrenal stress index
Correct answer: Full thyroid panel: TSH, free T4, free T3, reverse T3, and thyroid antibodies
A full thyroid panel assesses production, conversion, and autoimmune activity, giving a more complete picture than TSH alone.
Question 2: In functional nutrition, elevated fasting insulin with normal fasting glucose is an early indicator of what condition?
- Type 1 diabetes
- Insulin resistance (Correct answer)
- Hypoglycemia
- Adrenal insufficiency
Correct answer: Insulin resistance
Elevated fasting insulin with normal glucose indicates the pancreas is working harder than normal to maintain glucose levels, a hallmark of early insulin resistance.
Question 3: Which marker in a comprehensive metabolic panel (CMP) specifically reflects liver synthetic function?
- ALT
- AST
- Albumin (Correct answer)
- Bilirubin
Correct answer: Albumin
Albumin is produced by the liver, and low serum albumin levels indicate impaired liver synthetic capacity or malnutrition.
Question 4: A functional nutrition client with elevated RBC (red blood cell) magnesium but low serum magnesium most likely indicates what?
- Adequate total body magnesium
- The body is shifting magnesium from tissue to blood
- Cellular magnesium depletion with compensatory retention (Correct answer)
- Normal variation with no clinical significance
Correct answer: Cellular magnesium depletion with compensatory retention
Low serum magnesium with preserved RBC magnesium can indicate early depletion where the body is drawing from intracellular stores to maintain serum levels.
Question 5: Which test is considered the gold standard for assessing iron stores in the body?
- Serum iron
- Hemoglobin
- Ferritin (Correct answer)
- Transferrin saturation
Correct answer: Ferritin
Ferritin is a storage protein for iron, and its serum level directly reflects total body iron stores, making it the most reliable marker.
Question 6: In functional nutrition labs, an elevated fasting triglyceride-to-HDL ratio is associated with which metabolic pattern?
- Optimal fat metabolism
- Insulin resistance and metabolic syndrome (Correct answer)
- Hypothyroidism
- Vitamin D deficiency
Correct answer: Insulin resistance and metabolic syndrome
A high triglyceride-to-HDL ratio is a well-validated surrogate marker of insulin resistance and small dense LDL particle pattern.
