These measurements assess your liver health.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What does the liver do?&nbsp;<\/strong><\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The liver is a vital organ located in the upper right area of the abdomen, just below the diaphragm. It plays a crucial role in detoxifying harmful substances from the blood, metabolizing carbohydrates, fats, and proteins, and producing bile to aid in fat digestion. Additionally, it synthesizes important proteins, stores vitamins and minerals, supports immune function, and regulates various hormones. Overall, the liver is essential in maintaining metabolic balance, detoxifying the body, and supporting digestion and immune function.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span

They help in the early detection of liver diseases, such as hepatitis and cirrhosis, by measuring levels of enzymes, proteins, and bilirubin in the blood. These tests also monitor the progression of existing liver conditions and the effectiveness of treatments. Additionally, liver function tests can identify potential side effects of medications that may impact liver health. By providing essential information about liver performance, these tests enable healthcare providers to make informed decisions, ensuring timely intervention and effective management of liver-related issues.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"What_are_the_types_of_liver_function_tests\"><\/span><strong>What are the<\/strong> <strong>types of liver function tests?<\/strong><span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">To diagnose liver diseases, several tests are commonly used.

These tests help doctors find conditions like hepatitis, fatty liver, or cirrhosis. Understanding your LFT results is essential for managing liver health. Early detection can lead to better treatment and prevent further damage. If you&#8217;re concerned about your liver or your doctor recommends these tests, LFTs can give clear insights and help guide treatment. Always talk to your doctor to understand your results and keep your liver healthy.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>\n\n\n\n<p class=\"has-background wp-block-paragraph\" style=\"background-color:#fcb90033;font-size:20px\"><strong>Also Read: <a href=\"https:\/\/innovareacademics.in\/blog\/blood-sugar-in-human-body-part-1\/\" data-type=\"link\" data-id=\"https:\/\/innovareacademics.in\/blog\/blood-sugar-in-human-body-part-1\/\">Bad blood sugar in human body?
