Dengue infection has been known in India for a very long time. Frequent epidemic episodes occur especially in monsoons. All ages and both sexes are susceptible to dengue fever. Dengue/D.H.F (dengue hemorrhagic fever) is widely prevalent in our country. All four serotypes have been reported. It is one disease where worst outcome can be prevented by early diagnosis. It has been classified into three broad categories for management purpose and the classification is based upon clinical features and laboratory parameters.
Group A -patients with uncomplicated disease who need not be admitted. (Stable haematocrit but decreasing white blood cell count)
Group B -Patients for in hospital management. (Increase in haematocrit, decrease in w.b.c count and platelets)
Group C -Patients who require emergency treatment and urgent referral. (Rapidly falling platelet count, altered liver function tests, renal function tests and increasing haematocrit)
Hence laboratory tests play a centre role in early diagnosis of dengue fever and its complications. In our study we have emphasized upon the haematological parameters clinical signs and symptoms and its correlation with dengue infection.
