Elevated liver enzyme levels on a Liver Function Test (LFT) may indicate liver inflammation or damage. The most commonly measured enzymes are alanine aminotransferase (ALT) and aspartate aminotransferase (AST), which are released into the bloodstream when liver cells are injured. High levels of these enzymes can be caused by conditions such as hepatitis, fatty liver disease, alcohol use, or medication effects. Treatment depends on addressing the underlying cause, such as managing viral infections, reducing alcohol consumption, or stopping harmful medications. Early detection and treatment can prevent further liver damage.

Low albumin levels in a blood test can indicate several underlying health issues. Albumin is a protein made by the liver, and it plays a critical role in maintaining fluid balance and transporting vital substances. When albumin levels are low, it can be a sign of liver disease, kidney problems, malnutrition, or chronic inflammation. Low albumin can lead to symptoms like swelling (edema), fatigue, and poor healing. Treating low albumin depends on addressing the root cause, such as improving nutrition, managing kidney or liver disease, or reducing inflammation.

The Erythrocyte Sedimentation Rate (ESR) test measures the rate at which red blood cells settle at the bottom of a test tube. High ESR levels indicate inflammation in the body, which can be caused by infections, autoimmune diseases, or cancers. Low ESR levels may suggest conditions like congestive heart failure or blood disorders. Both high and low ESR levels require further investigation to identify underlying health issues. The test alone does not diagnose a condition but provides clues about the presence of inflammation or other systemic problems.

A low INR (International Normalized Ratio) level indicates that your blood is clotting faster than normal. This can increase the risk of developing blood clots, potentially leading to dangerous conditions such as deep vein thrombosis (DVT), pulmonary embolism, or even stroke. Low INR levels may occur due to certain medications, liver disease, or conditions that affect blood clotting. Treatment typically involves adjusting medications like blood thinners or addressing any underlying conditions. It’s important to monitor INR levels regularly, especially for patients on anticoagulants, to maintain a healthy balance between preventing clots and avoiding excessive bleeding.
