Blood Tests for Liver and Kidney Function

Liver function tests are used to evaluate the health of your liver and detect diseases like hepatitis, cirrhosis, or fatty liver. These tests measure enzymes and proteins that help doctors understand if the liver is damaged or diseased. They help diagnose liver conditions early, allowing for timely treatment.

The frequency of blood tests for liver and kidney function depends on your health status and risk factors. If you have a history of liver or kidney disease, regular tests may be recommended. Otherwise, your doctor might suggest testing every year as part of your routine health checkup.

Creatinine levels in blood tests are used to assess kidney function. High creatinine levels can indicate kidney damage or disease, as the kidneys are not filtering waste properly. Your doctor will interpret your creatinine levels in combination with other tests to evaluate kidney health.

Kidney problems often have no symptoms in the early stages, but as they progress, symptoms may include swelling in the legs or ankles, fatigue, changes in urination, and nausea. Blood tests for kidney function can help identify issues before symptoms become severe.
