Now, if we're talking liver, what type of clinical presentation do you think we're going to see in our patient? If you said jaundice, you're right. With liver disease, we're going to see patients with jaundice, they could have itchy skin, abdominal pain. They might even have Ascites. Remember when the abdomen is full of fluid, not that it would look like that. <laugh> um, we'd also see, of course, as I mentioned, if someone came in and was seeking treatment for alcohol abuse disorder, uh, the GGT is monitored. And if a patient has a drug overdose, we know that medications are metabolized by the liver. And the GGT can tell us how those hepatocytes are actually responding. We talked about bone disease differentiation because GGT won't be present if someone has bone disease with an elevated Alk Phos. It also would be indicated in someone of biliary tract damage.They're going to have a lot of abdominal pain. Pretty typical.
Normal therapeutic values are between 5 and 40 units per liter. It's collected in a serum separator tube. Lab values will be increased when there's a disease process of the liver. Most often, it could also be in cases of pancreatitis. Liver diseases are going to be cirrhosis, hepatitis fatty, liver disease, even if it's non-alcoholic and if there's tumors or cancer present, Cholestasis is when the bile ducts are blocked. And, that is also going to increase our GGT value. Now, it's not always a disease process that causes an increase in these lab values. It could be someone that's smoking, certain medications, and then it's definitely present in someone that has recently consumed a large amount of alcohol. This lab value would be decreased if someone has malnutrition. So, that means that the liver isn't metabolizing as well. It can also be completely unrelated to disease. GGT, remember the gamma glutamyl transferase, it's an enzyme that's measured in the blood that's most abundantly present in liver tissue produced by hepatocytes. Our normal value is between 5 and 40 units per liter, and it's related in its increased value to alcohol consumption and liver disease presentation. Malnutrition is often the cause of a decreased value. Now, you all did so great today. We love you guys now, go out and be your best self and as always, happy nursing!
