Blood plasma test

A blood plasma test involves analyzing the liquid portion of your blood, called plasma, which contains water, electrolytes, proteins, hormones, and waste products. This test helps doctors assess your overall health, diagnose medical conditions, monitor diseases, or check how well your organs are functioning. Plasma tests can provide information about your immune system, liver and kidney function, and the balance of substances in your body. It typically requires a blood sample drawn from a vein, and results can help guide treatment decisions or further testing.
