I am 41 year old female, had blood tests for insurance, and got standard letter back that explains nothing and has just left me worried - GGT 133 (normal supposidly 6-42), cholesterol 6.4 (optimum 5), hdl cholesteral 2.4 (1.2-1.7), ldl cholesteral 3.2 (upto 3.0). Am I really unhealthy? I had just come back from a holiday - lots to drink and eat!!!
