A C-Reactive Protein (CRP) test measures the level of CRP in the blood, an indicator of inflammation in the body. Normal CRP levels are typically less than 10 mg/L, with values below 3 mg/L considered optimal for general health. Elevated CRP levels may indicate inflammation caused by infection, injury, or chronic diseases like rheumatoid arthritis or cardiovascular disease. Regular monitoring of CRP levels helps assess the risk of developing conditions related to inflammation. Maintaining normal CRP levels through a healthy lifestyle, including a balanced diet and regular exercise, is crucial for reducing inflammation and supporting overall health.

The Thyroid-Stimulating Hormone (TSH) blood test measures TSH levels to assess thyroid function. Normal TSH levels typically range between 0.4 and 4.0 mIU/L, but these can vary slightly depending on the laboratory and age. Maintaining normal TSH levels is crucial for regulating thyroid hormones (T3 and T4), which control metabolism, energy levels, and overall health. Abnormal TSH levels can indicate conditions such as hypothyroidism or hyperthyroidism. Monitoring TSH levels is essential for diagnosing thyroid disorders and guiding treatment to ensure optimal thyroid function and health.

Low calcium levels in a bone profile blood test, known as hypocalcemia, can indicate various health concerns. Calcium is essential for bone health, muscle function, and nerve signaling. Low levels may result from conditions like vitamin D deficiency, hypoparathyroidism, or kidney disease. Symptoms of hypocalcemia can include muscle cramps, numbness, and fatigue. Treatment focuses on addressing the underlying cause, such as increasing dietary calcium, vitamin D supplements, or managing chronic health issues like kidney disease. It’s important to seek medical advice if low calcium levels are detected, especially if symptoms are present.

High bilirubin levels in a liver function test (LFT) indicate potential liver dysfunction or other underlying health issues. Bilirubin is a yellow pigment produced during the breakdown of red blood cells. When the liver isn’t functioning properly, bilirubin builds up in the blood, leading to jaundice (yellowing of the skin and eyes). Elevated bilirubin may signal conditions such as liver disease, bile duct obstruction, or hemolytic anemia. Treatments focus on addressing the underlying cause, such as improving liver function, treating infections, or removing blockages in the bile duct.
