Hi Sean
It will differ from lab to lab
PSA should be under 4 but if you do it yearly it should not be going up but staying around the same level. In other words, if it is one this year but 2 next year, it may show that there is a problem even though it is lower than normal (4)
For cholesterol a value of less than 200 mg/dL is desirable. Levels over 240 mg/dL may put you at almost twice the risk of heart disease as someone with a level less than 200 mg/dL. High LDL cholesterol levels may be the best predictor of risk of heart disease. If you have known heart disease, peripheral vascular disease (blockages in the blood vessels of the extremities), or diabetes, your LDL cholesterol should be below 100 mg/dL. If you have 2 or more heart-disease risk factors (smoking, high blood pressure, low HDL, a family history of heart disease, are a man over 45 or woman over 55), your LDL should be below 130 mg/dL. If you have none or 1 of the risk factors listed, your LDL cholesterol should be below 160. HDL cholesterol levels more than or equal to 60 mg/dL will take away the increased risk from one risk factor and decrease your risk of heart disease. Levels below 40 mg/dL add a risk factor. Triglyceride levels are also becoming an important predictor of risk for heart disease. Even if you have low LDL and high HDL cholesterol, high triglyceride levels may put you at risk. Normal triglyceride levels are less than 150 mg/dL and can be incorrectly elevated if a 9-12 hour fast was not completed.
