A C-reactive protein (CRP) blood test measures the level of CRP, a substance produced by the liver in response to inflammation. Elevated CRP levels indicate inflammation in the body, which can be caused by infections, chronic diseases like arthritis, or cardiovascular conditions. While normal CRP levels are generally below 3 milligrams per liter (mg/L), higher levels may signal acute inflammation or an increased risk of heart disease. CRP tests are used to assess the severity of inflammation and guide diagnosis and treatment plans, making them crucial for monitoring overall health.

A bilirubin blood test measures the level of bilirubin, a yellow pigment produced during the breakdown of red blood cells. This test helps assess liver function, as bilirubin is processed and removed by the liver. Elevated bilirubin levels may indicate liver or bile duct problems, such as hepatitis, cirrhosis, or gallstones. Normal bilirubin levels are typically below 1.2 milligrams per deciliter (mg/dL). Higher levels can lead to jaundice, causing yellowing of the skin and eyes. Monitoring bilirubin levels is essential for detecting liver dysfunction and preventing complications.

Hemoglobin is a protein in red blood cells responsible for transporting oxygen throughout the body. Normal hemoglobin levels range from 13.8 to 17.2 grams per deciliter (g/dL) for men and 12.1 to 15.1 g/dL for women. Low hemoglobin may indicate anemia, leading to fatigue, weakness, and shortness of breath. High hemoglobin levels, on the other hand, could suggest conditions such as dehydration, lung disease, or heart disease. Regular monitoring of hemoglobin through blood tests is crucial for identifying potential health issues early and maintaining overall health.

Triglycerides are a type of fat found in the blood. When you eat, your body converts excess calories into triglycerides, which are stored in fat cells. High triglyceride levels can increase the risk of heart disease, stroke, and pancreatitis. Normal levels are below 150 mg/dL, while borderline-high is 150-199 mg/dL, and high levels are 200 mg/dL or more. Managing triglycerides involves healthy lifestyle choices, such as maintaining a balanced diet, regular exercise, and reducing alcohol intake. Monitoring triglyceride levels through routine blood tests is crucial for maintaining heart health.
