Chikungunya Virus (ChikV) IgG/IgM Rapid Test is a rapid immunochromatographic assay for the simultaneous detection of IgG and IgM antibodies to Chikungunya virus in human whole blood, serum or plasma. The assay is used as a screening test for Chikungunya viral infection.
For professional use only.
For in vitro diagnostic use only.
Chikungunya virus is a mosquito-transmitted alpha virus belonging to the Togaviridae family, first isolated in Tanzania in 1952. Three lineages with distinct genotypic and antigenic characteristics have been identified. Chikungunya virus is endemic to some parts of Africa and causes recurrent epidemic waves in Asia and the Indian subcontinent. At the end of 2013 the virus emerged in the Americas. Human beings serve as the main chikungunya virus reservoir during epidemic periods. In Africa, some animals constitute the virus reservoir during non-epidemic periods sustaining virus circulation. Clinical signs of chikungunya virus infection include sudden onset fever and severe arthralgia (joint pain) affecting mainly the extremities but also the larger joints. Erratic, relapsing, and incapacitating joint pain is the hallmark of chikungunya virus. Up to 12% of patients still have chronic joint pain three years after the onset of their illness. Other symptoms of the infection (headache, fatigue and rash) are common among many arborviral infections including chikungunya virus. There is no specific therapy for chikungunya virus infection. Patients are symptomatically treated with antiinflammatory medication. The death rate is not high, but excess mortality has been observed occurring together with larger chikungunya virus outbreaks. Diagnosis is based on the detection of virus by molecular methods or by virus culture in the first days of infection before an antibody response is evident. IgM antiChikV is detectable two to three days at the onset of symptoms and persist for several weeks up to three months. ChikV specific IgG appears soon after IgM antibodies and persist for years.
ChikVs IgG/IgM Rapid Test is a new generation rapid Immuno-chromatographic test using recombinant chikungunya viral antigens of both wild type and mutant type to detect specific antibody response.

Sample Collection&Storage
The ChikV IgM/IgG Rapid Test Kit can be performed on plasma, serum, or whole blood.
Serum and plasma:
Test specimens as soon as possible after collecting. Store specimens at 2°C -8°C if not tested immediately. Specimens can be stored at 2°C -8°C for up to 5 days. The plasma and serum specimens should be frozen at -20°C for longer storage.
Avoid multiple freeze-thaw cycles. Prior to testing, bring frozen specimens to room temperature slowly and mix gently.
Specimens containing visible particulate matter should be clarified by centrifugation before testing.
Do not use samples demonstrating gross lipemia, gross hemolysis or turbidity in order to avoid interference on result interpretation.
Whole Blood:
Whole blood can be obtained by either fingertip puncture or venipuncture. Whole blood specimens should be stored in refrigeration (2°C-8°C), if not tested immediately. The specimens must be tested within 24 hours of collection.
Bring tests, specimens, buffer and/or controls to room temperature (15- 30°C) before use.
1. Remove the test from its sealed pouch, and place it on a clean, level surface. Label the test with patient or control identification. For best results, the assay should be performed within one hour.
2. Transfer 1 drop of whole blood, serum or plasma specimen to the specimen well (S) of the device with the provided disposable pipette, then add 1 drop of buffer and start the timer.
3. Wait for colored line(s) to appear. Interpret the test results in 15 minutes. Do not read results after 20 minutes.
