Package: Advance Fever Package. Tests: 70 parameters, 8 components. Price: From 1199. Fasting: Not required. Sample: Blood and urine, single visit. Reports: 12 hours, digital. Home collection: Free across Greater Noida. Lab: NABL-accredited. The dengue marker in this package has an expiry date measured in days of illness, and in a city as spread out as Greater Noida what usually spends those days is the journey. Someone waits to feel well enough to travel, then waits for a lift, and a test that would have worked on day three is taken on day seven. A collection at your own address, reported 12 hours later, keeps the window from being spent on logistics. On the Basic Fever Package's base this adds Dengue NS1 Antigen (Rapid), Typhidot - Serum (IgG - IgM BY ELISA) in place of Widal, and full Kidney Function Test and Liver Function Test profiles — liver because dengue and typhoid both disturb transaminases, kidney because days of poor oral intake move urea, creatinine and electrolytes. Already past day 6? Read the timing section, then consider the Comprehensive Fever Package, which adds Dengue IgM and IgG. ## Dengue NS1 Antigen: Why the Day of Fever Decides the Test Dengue NS1 Antigen (Rapid) detects a non-structural protein the virus itself manufactures, so it finds the virus rather than your response to it. That is why it works early and stops working later: NS1 is detectable from roughly day 1 to day 7 of fever and fades as antibodies appear. Dengue IgM shows up around day 4 to day 5 and indicates current or recent infection. Dengue IgG suggests past infection, or a secondary infection when it rises alongside IgM. The consequence is concrete: someone presenting on day 6 can be NS1-negative and IgM-positive, and an NS1-only test would have called them negative. Inside day 1 to day 5 this package suffices; beyond that the Comprehensive Fever Package, which carries all three markers, has a real advantage. A negative NS1 early on does not rule dengue out, and no antigen or antibody result replaces clinical monitoring: falling platelets, a rising haematocrit and warning signs guide treatment. ## Typhidot by ELISA Instead of Widal Typhidot - Serum (IgG - IgM BY ELISA) detects IgM and IgG antibodies specific to Salmonella typhi, turns positive earlier in the illness than Widal, and does not react across other Salmonella species. Widal (Slide Agglutination Test), used in the Basic Fever Package, cross-reacts with other Salmonella, stays positive after past infection or vaccination, is frequently falsely positive in endemic areas, and needs paired samples 7 to 10 days apart. One caveat: blood culture remains the reference standard for typhoid, and this package does not include it. If your doctor needs certainty before starting an antibiotic, ask for one, drawn before the first dose — antibiotics taken beforehand sharply reduce the yield. ## Blood Picture - Peripheral Smear Examination This package looks for malaria twice, by two methods that fail in different ways — and that is the clearest reason the slide is in it. MALARIA ANTIGEN -EIA detects parasite protein, which can linger for some days after treatment has cleared the infection, so a positive may be a trace of something already treated. The Hemoparasites finding on Blood Picture - Peripheral Smear Examination is the other method: a qualified pathologist prepares a slide and looks for the parasite inside your red blood cells. What is seen under the microscope is present now. Five findings are reported: Red Blood Cells, White Blood Cells, Platelets, Hemoparasites and a written Impression. The platelet finding matters second, and specifically in dengue: falling platelets are the key monitoring parameter, and automated counters misread clumped platelets as a dangerously low count — the pathologist catches that artefact before anyone acts on a false alarm. Where the count shows anaemia, the red cell appearance points at a cause: microcytic cells iron deficiency, macrocytic cells B12 or folate deficiency, sickle shapes sickle cell disease, blast cells possible leukaemia. Over 50% of Indian women aged 15–49 are anaemic (NFHS-5, 2019–21). None of it is automated: a person makes each slide and reads it, which is why it is the line item dropped first when a package is priced down. ## The Other 5 Components CBC with ESR (21): Haemoglobin, platelet count, haematocrit, the white cell differential and ESR — the pattern-reading core of a fever workup. Liver Function Test (12): Bilirubin, SGOT, SGPT, GGT, ALP and proteins; transaminases commonly rise in both dengue and typhoid. Kidney Function Test (12): Urea, creatinine, electrolytes and GFR, reflecting fluid shifts in febrile illness. Complete Urine Analysis (17): Nitrites, leukocytes, pus cells, protein and casts — identifies urinary infection as the fever source, and detects overt proteinuria but not microalbuminuria. ## Limitations No Dengue IgM or IgG, no chikungunya IgM, scrub typhus, leptospira, COVID-19 or influenza test, no blood culture, no Procalcitonin, no CRP, no imaging. Fever with breathlessness, vomiting, bleeding, drowsiness or falling urine output needs urgent in-person assessment, not a repeat test. ## Sources NFHS-5, 2019–21 Content last reviewed: October 2026
