Introduction

Liver and kidney function tests typically use red-top blood collection tubes. Blood draws can determine the levels of enzymes such as transaminases and bilirubin in the blood. In addition, fasting is usually required before undergoing liver function blood tests to avoid affecting the test results. In daily life, it's important to develop healthy eating habits, avoiding overeating and consuming high-calorie, high-fat foods, to prevent adverse effects on health.

Red-top blood collection tubes are typically used for liver and kidney function tests.

Blood collection tubes usually come in different colors, such as red, yellow, green, etc., each containing different additives and intended for specific types of tests. The red-top tube contains no additives and is suitable for routine blood testing, including assessments of liver and kidney function, blood glucose, and lipid levels. Therefore, red-top tubes are commonly used when testing liver function. During liver function testing, blood samples allow measurement of levels of enzymes such as transaminases, bilirubin, albumin, and others. Changes in these levels help detect conditions such as liver disease or renal failure. Additionally, blood tests can measure triglycerides, cholesterol, and other indicators to evaluate a patient's overall health, enabling early detection and timely treatment of diseases.

Moreover, fasting is generally required before undergoing liver function blood tests to avoid affecting the accuracy of results. It is important to maintain healthy eating habits in daily life, avoiding overeating and consuming high-calorie, high-fat foods, to protect overall health.
