Growing sedentary lifestyles, increasing stress levels at work place, tempting and enticing food displays, growing disposable incomes, increased addictions to automobiles, all indicate that we give to our body more than what it needs. This has given rise to obesity, diabetes, high blood pressure and a host for many other lifestyle disorders. With advanced tests and technologies, clinical laboratories can help in identifying various disorders accurately which can be treated completely or at least the progress can be delayed.
