Parvovirus B19 IgM ELISA Kit

Full Name: Parvovirus B19 IgM ELISA Kit
Reactivity: Human
Sample Type: Serum
Sensitivity: 0.63 DU/ml


Parvovirus B19 is a member of the genus Erythrovirus and family Parvoviridae, it is a small single stranded DNA virus which only infects humans. Majority of the virus is transfected via the respiratory secretions, however, some is found to go through blood transfusions, from mother to baby via the placenta and bone marrow transplants. There is zero chance of this virus to be transferred from humans to pet animals since it displays no cross reactivity whatsoever. Parvovirus B19 has been associated with a number of autoimmune diseases, immunocytopenia in immunocompromised patients, however, one of the commonest infections discovered is erythema infectiosum that is present in children.


Human parvovirus B19 IgM ELISA kit is intended for analysis of IgM class of antibodies against parvovirus B19 in serum. This assay has a minimum analytical sensitivity limit of 0.63 DU/ml.


All reagents supplied need to be stored at 2 °C – 8 °C, unopened reagents will retain reactivity until expiration date. Do not use reagents beyond this date.

The minimum detection sensitivity level of IgM antibodies to parvovirus B19 using current parvovirus IgM ELISA kit was 0.63 DU/ml. The dynamic range for this assay was to a specific cut-off point.


– Positive: >12 DU. [Mean OD patient > 1.2 × CO]
– Grey Zone: 9 – 12 DU. [0.90 × CO ≤ Mean OD patient ≤ 1.2 × CO]
– Negative: <9 DU. [Mean OD patient < 0.90 × CO.]
– Cut-Off: 10 DU
– Assay Dynamic Range: 0.63 – 60 DU/mL
– Specificity of Antigen (Cross Reactivity): No cross reactivity with HSV 1 and 2, Varicella zoster Virus and Epstein Barr Virus (VCA), RSV, CMV and TBE.
– Analytical Sensitivity: 0.63 DU/mL (OD450 = 0.034).
– Diagnostic Specificity: 100%
– Diagnostic Sensitivity: 100%

I am a first time user and found that your instruction manual was very easy to follow. The insulin ELISA assay performed well and I was happy with the results that were generated.

J. Thomas
Senior Technician / Addenbrooke’s Hospital

I carried out a pilot study comparing the performance of many ELISA assay's from different suppliers and found your kits to be one of the better performers. We observed good linearity and tight replicates.
