Can anyone help me understand cholesterol test results please?

[LumpyandBumps]

Good evening,
I had a routine blood test for liver function due to medication.
I checked my results online this evening, which show the result of all 3 tests to be ‘borderline’ with no further action required.
I have looked at the details and I seem to be well within stated bandwidth for 2 of them.
It seems to be just the Lipid test, which has 2 results which are above ‘high reference limits’
I have been trying to understand the figures and googled for help, but I don’t know how bad my results are as some of the information seems contradictory.
The problem ones are:
Serum HDL cholesterol level 1.89 ( reference limit 0.9 - 1.45)
Calculated LDL cholesterol level 4.78 ( reference 0.0 - 4.0)
I didn’t even know they were testing cholesterol. It was not a fasting blood test.
Thanks in advance.

These results are not a big concern, and many people have borderline lipids for years without issues. However, this could be a prompt to look at lifestyle tweaks

Reducing saturated fats (e.g. swap butter for olive oil). Adding foods that support LDL reduction (e.g. oats, nuts, soluble fibre). Moderate exercise (e.g. 30 min walk 5x/week).
Of your on medication that affects lipids (e.g. antipsychotics, steroids, or hormone therapy), that may be contributing.

Thank you very much for this.
