The influenza virus spreads predominantly in the winter season of each year, and many people suffer from this acute viral infection. Serious cases of the illness carry the risk of pneumonia in the elderly, and may cause complications of encephalitis and encephalopathy in small children. To prevent increased severity of infection, complications and secondary infections, early diagnosis and treatment at the medical facility must be commenced at an early stage and there have been higher needs for rapid testing in the early stage of infection.
SPOTCHEM FLORA FluAB released by ARKRAY, Inc. (hereafter, 'ARKRAY') is a kit that detects Type A and Type B influenza virus antigens in fluids obtained by nasal swabs or nasal aspiration. Early determination (fastest result: 1.5 minutes) is now possible due to high sensitivity measurement employing the TRF method* with the dedicated measurement instrument SPOTCHEM FLORA SF-5510. By detecting viral infection, for which determination used to be difficult in the early stage, both rapidly and with high detection performance, it is considered the kit shall be beneficial in improving diagnosis efficiency, alleviating the burden on the patient and reducing opportunities for the spread of the influenza virus.
ARKRAY shall continue contributing to rapid diagnosis and appropriate treatment in the front line of the medical field through the development of new diagnosis systems.
*Time-resolved fluorescence method
High detection performance
High detection performance is realized through the TRF method employing europium (Eu) as a labeling substance, which has a long fluorescence life time and fluorescence wavelength that allows for easy detection of the virus. Using conventional methods the determination of infection was difficult unless testing took place after the viral load increased in the body. However, it is now possible to determine infection even with the low viral load of early infection.
Shortened test time
The time for testing, which used to be 10 minutes or more with previous products (previous model and measurement method of ARKRAY products), is now shortened to 1.5 minutes (fastest test time that is for a sample with high viral load). Upon early detection of a positive reaction between 1.5 to 6 minutes the results of early determination are printed out prior to final determination (10 minutes), contributing to shortened test time and lighter burden to the patient in terms of waiting time.
Simple and automatic measurement
After dripping the pre-processed sample on the cartridge, the result is automatically determined by simply inserting the test cartridge in the instrument. Visual determination and time management which had been conducted manually is now no longer necessary.
Prevents mix-up of samples
Names or symbols can be entered on the cartridges. Since this information is read in the instrument together with the inspection result, the cartridge is useful in preventing the mix-up of samples.
Alleviating the burden of patients
In order to alleviate pain at the time of sample collection, soft-tipped flocked swabs are included.
ARKRAY has been selling the SPOTCHEM series of simple testing devices for immediate testing in clinics since 1988. SPOTCHEM FLORA SF-5510 realizes highly sensitive and rapid measurement through the TRF method, supporting the testing of infectious diseases at the site of medical treatment.
