These organs are essential for maintaining overall metabolic balance, eliminating toxins, controlling fluids, and filtering waste. When symptoms point to an underlying medical condition or are part of routine health screening, doctors frequently recommend a blood test to assess liver and kidney function. Early testing aids in identifying anomalies before they develop into major medical problems.<\/span><\/p>\n<h2><b>What Is a Liver and Kidney Function Blood Test? Purpose, Results &amp; Cost<\/b><\/h2>\n<p><b><\/b><span style=\"font-size: inherit;\">The effectiveness with which the kidneys and liver carry out their vital functions is referred to as kidney and liver function. Normal digestion, balanced electrolytes, appropriate waste removal, and toxin elimination are all guaranteed by healthy kidney and liver function. Due to the close relationship between their functions, doctors frequently perform laboratory tests on both organs at the same time.<\/span><\/p>\n<h2><b>What Is a Liver and Kidney Function Blood Test?<\/b><\/h2>\n<p><span style=\"font-weight: 400;\">A blood test for liver and kidney function evaluates the performance of the organs by measuring particular enzymes, proteins, and waste products in the blood. Typically, this test combines:<\/span><\/p>\n<ul>\n<li><span style=\"font-weight: 400;\">Tests of Liver Function (LFTs)<\/span><\/li>\n<li><span style=\"font-weight: 400;\">Tests of Kidney Function (KFTs)<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><\/li>\n<\/ul>\n<p><span style=\"font-weight: 400;\">When combined, they offer a thorough assessment of liver and kidney health and aid in the early detection of inflammation, infection, or organ damage.<\/span><span style=\"font-weight: 400;\"><br \/>\n<\/span><span style=\"font-weight: 400;\">Liver and kidney tests are ways of measuring how these organs are functioning, most often carried out through blood and urine testing.
