Your total is high because your good
cholesterol levels are
high, which is a good thing. You LDL or bad
cholesterol is within normal ranges and I calculate your TGLs at 145 which is also good.
Overall, very good numbers. I wouldn't get too excited with a slightly high total cholesterol along with a high HDL, normal LDL and TGL unless you have heart disease in which case you should have an LDL under 100. If you are otherwise in good health, these look good to me.
