Tsh high/ egfr low & slight hemolysis, what does all this mean?

Low thyroid : A high TSH almost always means that there is too little thyroid hormone in the blood. It would not usually cause decreased kidney function as suggested by a low egfr (estimated glomerular filtration rate) or breakdown of red blood cells (hemolysis). The hemolysis and decreased kidney function might be related however. Your situation is and complex and potentially serious - see your doctor!
