A routine blood test usually only test for some general features, like potassium, sodium, creatinine, urea, C-reactive protein and a few other. It does often make a blood count of both red blood cells and white blood cells too. In that way it can detect leukemia.
Standard blood tests measure blood sugar (glucose), but not blood fats. People with HIV are testing their blood sugar and blood fat levels more frequently because ARVs seem to cause abnormally high levels. This is especially true for the ARVs called protease inhibitors.
