I too have often wondered if any action is taken especially as we would never do a cholesterol in isolation
One question - was it an early morning blood test without breakfast and no big meals the night before? If not again of limited value
Do let us know the outcome but please remember it isnt just about your certificate. If this was a fasting cholesterol you do need to follow it up and get advice - managing lipids and cholesterol especially in the younger male is crucial for preventing cardiovascular disease later on
