Entamoeba Histolytica IgG ELISA Kit

Full Name: Entamoeba Histolytica IgG ELISA Kit
Reactivity: Human
Sample Type: Serum, Plasma
Sensitivity: diagn. > 95%


Entamoeba histolytica is regarded as a causative agent of amoebiasis and it is an anaerobic parasitic amoebozoa. It is only trophozoites which is the virulent strain that has the ability to invade the intestinal wall, resulting in forming ulcers that can later be released later as either mucous or blood into the faeces.

It can lead to wide spectrum of illnesses which are essentially intestinal conditions which can be caused by ameboma, acute proctocolitis, symptomatic non-invasive infection, perianal ulceration, chronic non-dysenteric colitis and asymptomatic infection. ,Stool samples are commonly used for diagnosis using a number of microscopy techniques.


Human Entamoeba histolytica IgG ELISA kit can be used for in-vitro quantitative detection of IgG antibodies to entamoeba histolytica (Entamoeba histolytica-IgG) in samples of plasma and serum. This assay has a minimum analytical sensitivity limit to a diagn. > 95%.


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.

  • Entamoeba Histolytica Coated Microplate (IgG).
  • Sample Diluent.
  • Stop Solution.
  • Washing Buffer (20x Conc.).
  • Entamoeba Histolytica Protein A Conjugate.
  • TMB Substrate Solution.

The minimum detection sensitivity level of human IgG antibodies against entamoeba histolytica (entamoeba histolytica IgG) using current Entamoeba histolytica IgG ELISA kit was to diagn. > 95%. The dynamic range for this assay is to a cut-off index point.

– Diagnostic Specificity: 98.0 %
– Diagnostic Sensitivity: 100.0%
– Interferences: No interferences was observed with lipemic, hemolytic and icteric.
– Cross Reactivity: No cross reactivity.

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.
