Serum 25-OH Vitamin D Test at Chughtai Lab

The Serum 25-OH Vitamin D test is the most reliable blood test for evaluating the body’s vitamin D status. It measures the level of 25-hydroxyvitamin D [25(OH)D], the primary circulating form of vitamin D, which reflects vitamin D obtained from sunlight exposure, diet, and supplements. This test is considered the gold standard for diagnosing vitamin D deficiency, insufficiency, and monitoring vitamin D therapy.

Vitamin D plays a crucial role in maintaining healthy bones and teeth by promoting the absorption of calcium and phosphorus. It also supports muscle function, immune health, nerve function, and overall well-being. Vitamin D deficiency is common in Pakistan due to limited sun exposure, indoor lifestyles, dietary factors, and certain medical conditions. If left untreated, low vitamin D levels can increase the risk of osteoporosis, osteomalacia, muscle weakness, fractures, and other health complications.

Doctors commonly recommend the Serum 25-OH Vitamin D test for individuals with persistent bone pain, muscle weakness, fatigue, frequent fractures, osteoporosis, chronic kidney disease, malabsorption disorders, obesity, or those at increased risk of vitamin D deficiency. The test is also used to monitor patients receiving vitamin D supplementation and assess the effectiveness of treatment.

At Chughtai Lab, the Serum 25-OH Vitamin D test is performed using advanced automated immunoassay technology that provides accurate and reliable results. Supported by experienced laboratory professionals, qualified pathologists, and strict quality assurance standards, Chughtai Lab offers trusted vitamin D testing through its nationwide network of collection centers across Pakistan.
