I had my yearly physical this week and called for the blood work results today. The nurse said it's within limits. I guess that's OK but maybe someone like Rich can tell me in plain English about the results.
I'm 6'4" 265 lbs. Total Cholesterol 163
LDL 104
HDL 38
PSA 1.0
Tri's 105
Numbers look good to me, but understand the context: a middle aged man who is "average" for the USA has about a 1% heart attack or sudden death rate annually. It goes up with age. Cholesterol is only one risk and many people with normal cholesterol levels get heart attacks. It's usually expressed as a 5- or 10-year mortality of about 5% or 10%.
If you isolate choleserol and related lipid stuff, you can vary that projection from, say, 10% down as low as maybe 6%, or from 10% up to maybe 20% -- over 10 years. Bottom line is that playing with cholesterol even under the best circumstances allows you to improve odds by fractions of a percent per year. I'm excluding extreme situations here.
Anyhow, your numbers look good. A couple of additional prognostic tricks help sort out how important that HDL (good cholesterol -- it's a little bit low). One is to look at the ratio of total to low: 4.3, where under 4.5 is normal. The other is to look at total minus HDL which is 125 (normal). So all in all, your lipid levels look good.
Of course none of this has any effect on lifestyle, body weight and waist circumference, family history, diet, conditioning. blood pressure, etc. It's just a reassuring result for the blood lipid piece. (The PSA, of course, relates to presence of advancing prostate cancer and is normal; that test is also limited in its accuracy in a screening setting.)
Hope that's helpful.
