Borrelia Ig test

A rapid immunochromatographic device test for detection of total Ig antibodies against 3 species of Borrelia burgdorferi (B. burgdorferi sensu stricto, B. afzelii and B. garinii), causing Lyme borrelosis, in serum.
IgG appear about 10 weeks after the infection. IgG are absent in 50% of cases in the early stage. Their rate increase in the secondary stage and they are always present in the tertiary stage. They can be detected as long as the symptoms persist. IgM can be detected quickly (about 2 weeks after the infection). Their rate decrease quickly and they are not constantly present in the secondary and tertiary stages.
Within 3 to 6 weeks, Borrelia burgdorferi antibodies are produced and keep increasing for several months. A serologic testing in Lyme disease can be performed to detect Borrelia burgdorferi antibodies in serum.
  • Qualitative and quantitative results, detection of total Ig
  • Use of a mixture of native antigens (B31 strain) and recombinant proteins (proteins OspC, BmpA and p88/100 of the B31 strain)
  • Sensitivity: Global sensitivity 80%
    Early stage sensitivity 60%
    Secondary stage sensitivity 76%
    Late stage sensitivity 100%
  • Specificity: 94% on a population of healthy blood donors
  • One step test, results in 10 to 20 minutes
  • Shelf life 12 months
 
   

Borrelia burgdorferi IgG & IgM Dipstick Test

Immunoblot strip test for the detection of IgG and IgM antibodies against Borrelia Burgdorferi in human serum or plasma.
  • Specific recombining antigens of the 3 genospecies : B. burgdorferi sensu stricto, B. afzelii, B. garinii which allows the identification of the specific antibodies for the 3 spices.
  • Optimization of the quantity of each antigens in particular for the antigens under-represented in the Western Blot system (example : p100, p 39, p18 and mainly OspC)
  • 2 proposed protocols:
    short: 2 h of serum incubation
    long: overnight incubation of serum
  • Internal control of the reaction
  • Specificity: IgG 94%, IgM 97,5%
  • Shelf Life 12 months
 
   

Streptococcus A Dipstick Test

Immunochromatographic rapid dipstick test for the detection of Strep A antigen in throat swabs specimens to aid in the diagnosis of group A streptococcal infection.
  • Streptococus pyogenes which contains the lance field group A antigen that can cause serious infections such as pharyngitis, respiratory infection, endocarditis, meningitis and arthritis. Rapid diagnosis and early antibiotic therapy of group A Streptococcal infection appear to be the best means of preventing medical complications and reducing the spread of the disease.
  • Sensitivity 96,8% ; Specificity 94,7%
  • Negative predictive value 98,9%
  • Quality control: positive and negative control provided
  • Result in 5 minutes
  • Shelf Life 18 months
