Which LDL level is considered high?

• A. <110
• B. 110-129
• C. 130+
• D. 100-109

Answer: (C)

LDL cholesterol is considered high when it reaches 130 mg/dL or higher. This threshold comes from guideline classifications that group LDL levels as: under 100 mg/dL is optimal, 100–129 mg/dL is near/above optimal, 130–159 mg/dL is borderline high, 160–189 mg/dL is high, and 190 mg/dL or more is very high. So a level of 130 mg/dL or higher sits in the high category. The other ranges listed are all below that cutoff, so they aren’t labeled high according to these standards. Understanding this helps you see why 130+ is the right choice: it marks a level where clinicians start to consider more proactive steps to reduce LDL and lower cardiovascular risk.
