Till a few years back, diagnosing what condition a patient suffered from involved in doing a thorough study of his medical history. The basic algorithm of diagnostics still remains the same- but with molecular diagnostics, we’ve modified it to an extent where we can not only diagnose the patient with precision, but also provide treatment which will suit that individual the best.
Molecular diagnostics involves analysis of a patient’s biological markers present in the genome and proteome, which are the constituents of a person’s genetic code. The information thus obtained can not only aid in diagnosing the condition a patient may or may not be suffering from at present, but also helps in predicting the risk of diseases in the future, and is also being largely used to implement treatment options suitable to individual patients. These treatments are what come under the tag of personalized medicine.
