Lukourgus..........sorry if my answer has confused you.
Normal Serum cholesterol is about 5.5 nmol\L, but if it were me, i would be happy with 6.0 nmols.
The same with LDL....a touch on the high side......but wouldn't bother me.
Those results are fine as long as they don't get any higher.
Check again in 6 months.
