Final answer:
Liver function tests (LFTs) are blood tests that help to examine the health of the liver by checking the levels of specific enzymes like lactate dehydrogenase (LDH) and proteins in the blood, along with complete blood count (CBC) and ultrasound imaging.
Step-by-step explanation:
Liver Function Tests (LFTs)
LFTs, or liver function tests, are a group of blood tests designed to provide information about the state of a patient's liver. These tests assess the presence and levels of specific enzymes and proteins in the blood that can indicate liver damage or disease. One key enzyme is lactate dehydrogenase (LDH), which is found in many body tissues, including the liver; elevated levels may suggest liver damage. Furthermore, a complete blood count (CBC) can reveal infection through an elevated white blood cell count, while ultrasound can image intra-abdominal organs to check for any abnormalities.
The liver is essential for detoxification and the digestion of fats, producing bile which is necessary for breaking down fatty components in the food. The liver also processes vitamins and synthesizes plasma proteins. Hence, the proper function of the liver is crucial for overall health.
