BlueDiver Instrument IMMUNOBLOT KITS FOR DIAGNOSIS OF LYME BORRELIOSIS INFECTIOUS SEROLOGY IN NEW AUTOMATED SYSTEM FOR THE ANALYSIS AND EVALUATION OF IMMUNOBLOTS BlueDiver Instrument, Immunoblot Software and BlueBLOT-LINE Borrelia kits - a comprihensive solution for simple, fast and accurate analysis of immunoblots including evaluation
BlueBLOT-LINE Borrelia Immunoblot kits are optimized and validated for detection of IgG and IgM antibodies to recombinant antigens of Borrelia species and Anaplasma phagocytophila (HGA) in human serum and plasma. Lyme borreliosis (LB) is a multisystem infectious disease caused by spirochete Borrelia burgdorferi. The infection is transmitted by ticks of the genus Ixodes. Lyme borreliosis is characterized by early and late clinical symptoms: Early localised infection lasts days to weeks. The specific clinical sign of this phase is erythema migrans (EM), which appears in only 50% of patients. Early symptoms of the disease include flu-like symptoms, headaches and lymphadenitis. Early disseminated infection lasts weeks to months. Borrelia bacteria are disseminated by blood and lymphatic system (CNS, joints, heart, eye and skin secondary EM). In this phase, neuroborreliosis, neurofacialis paresis, borrelial lymphocytoma (swollen earlobes, knucklebones, etc.) and Bannwarth syndrome are the most frequently diagnosed symptoms. Late disseminated infection lasts months to years. Immunopathological changes occur. The typical diagnostic findings are acrodermatitis chronica atrophicans (chronic skin lesions ACA), chronic neuroborreliosis and borrelial arthritis. Human granulocytic anaplasmosis (HGA) is a disease caused by Anaplasma phagocytophila bacteria. Clinically, the disease can manifest itself in various ways from entirely asymptomatic to rather serious forms.

Nevertheless, it is sometimes possible to observe cross reactivity with other pathogens which can result in false positive results. The IgM test uses a highly specific and sensitive EBV marker (VCA-p18) to eliminate false positive Borrelia results, the IgG test uses the antigen TnN17 which is an important marker of syphilis infection.
