Is a reading of 4.5 normal for cholesterol levels?
Yes, Total cholesterol should be <5mmol/l. It would be more interesting to know your full lipid profile. The full lipid profile should always be taken into account when assessing cholesterol risk. The HDL and LDL needs to be taken into consideration. This is the TC:HDL ratio. You need a high level of HDL and a low level of LDL. You could have a low HDL and a high LDL and this could indicate high cholesterol risk later down the line.
