The standards of healthcare have evolved beyond comprehension. The sector has developed by leaps and bound, since the dawn of the 20th century. Not long ago, diseases that were supposed to be incurable such as tuberculosis, plague and typhoid are now avoided by a few vaccination shots during the childhood of an individual. Likewise, another deadly disease like tetanus, which was once considered mortal, can now be avoided with relative ease, by a few booster injections and immunization doses. With the ever appearing innovations and new developments, tests such as blood glucose level mapping and pulse oxygen level metering can now be done at home with relative ease, without getting entangled into the hassle of visiting a clinic.
