The Fever Profile 3 is an advanced and highly comprehensive diagnostic package designed for evaluating persistent, high-grade, or undiagnosed fevers, especially in cases where initial investigations (like Fever Profile 1 or 2) have not revealed a clear cause. This profile includes an extensive array of blood, urine, and sometimes serological tests that cover a wide spectrum of possible infections—bacterial, viral, parasitic, and even certain inflammatory or autoimmune conditions. In addition to routine tests like Complete Blood Count (CBC), ESR, Widal, Malaria Parasite/Antigen, Dengue NS1 & IgM/IgG, and Urine Examination, Fever Profile 3 may also include tests like Typhidot, CRP (C-Reactive Protein), Liver and Kidney Function Tests, Procalcitonin, and even blood cultures in some cases. It provides a detailed picture of the body's immune response, infection markers, and vital organ status. Fever Profile 3 is particularly valuable for clinicians dealing with complex or prolonged febrile illnesses, helping them narrow down the differential diagnosis and begin targeted treatment without delay.
