Question

Kevin is a 15-year-old who comes to your clinic concerned about the darkened thickened skin across the back of his neck. You know this is acanthosis nigricans. Kevin is also 67 inches and weighs 238lbs. Given this historical information what laboratory testing would be most appropriate for Kevin?

1) thyroid panel
2) hgb A1C
3) lipid panel
4) all of the above

Answer 1

Hgb A1C would be the most appropriate laboratory testing for Kevin.

Step-by-step explanation:

The most appropriate laboratory testing for Kevin would be option 2) hgb A1C. Acanthosis nigricans is often associated with insulin resistance, which can be indicated by an elevated hgb A1C level. This test measures the average blood sugar levels over a period of time.

Option 1) thyroid panel would be less relevant in this case because acanthosis nigricans is not typically associated with thyroid dysfunction. Option 3) lipid panel may be helpful in assessing Kevin's overall cardiovascular risk, but it is not directly related to the darkened thickened skin on the back of his neck.
