Having skimmed over, one indication that my GP isn't up to date is that the lipid test is no longer required to be a fasted test, whereas mine was. Interestingly the specialist lipid clinic has also asked for a fasting test.
I'm coming from the US, but the tests that are run by a doctor are often constrained by what the nearby laboratories offer. New, validated tests may be delayed until the relevant laboratories deem them to be cost-effective.
