Test Details: The analysis of body fluids plays a critical role in the diagnosis and prognosis of a disease. A change in concentration or composition of a particular biochemical constituent in body fluids is used as an indicator of a physiological or pathological condition. A particular component in body fluids can thus be considered as a marker for the detection of a disease. Detection of such markers at an early stage can lead to a prompt diagnosis, which can result in an appropriate therapeutic treatment.
