Question: is hdl of 100 good?
Answer: HDL is considered good because it takes the bad LDL out of your blood and keeps it from building up in the arteries. The standard recommendation has been to keep HDL levels high (40 to 60 milligrams per deciliter [mg/dL]) and LDL low (less than 100 mg/dL). (See "Lipid levels in adults.")
