Why Context Matters
FSH levels fluctuate significantly depending on the day of the menstrual cycle and can be suppressed by hormonal contraceptives or high doses of Biotin (Vitamin B7). A second opinion ensures that the test was timed correctly (usually Day 3 of the cycle) for accurate interpretation.
Lab ranges are statistical averages, not biological laws. "Normal" for a 20-year-old male isn't normal for a 60-year-old female.
