Liver function tests are blood tests used to help diagnose and monitor liver disease or damage. The tests measure the levels of certain enzymes and proteins in your blood.
Some of these tests measure how well the liver is performing its normal functions of producing protein and clearing bilirubin, a blood waste product. Other liver function tests measure enzymes that liver cells release in response to damage or disease.
Abnormal liver function test results don’t always indicate liver disease. Your doctor will explain your results and what they mean.
Tests of renal function have utility in identifying the presence of renal disease, monitoring the response of kidneys to treatment, and determining the progression of renal disease. According to the National Institutes of Health, the overall prevalence of chronic kidney disease (CKD) is approximately 14%. Worldwide, the most common causes of CKD are hypertension and diabetes.
A thyroid-stimulating hormone or TSH lab test can help determine whether you have either hyperthyroidism or hypothyroidism, both of which can interfere with your appetite, heart rate, and energy levels.
