Autoimmune haemolytic anaemias (AIHAs) are well-characterized disorders. They can be differentiated from one another and from other non-immune haemolytic anaemias by clinical, laboratory and serological testing. However, several misleading clinical presentations and/or serological findings may result in misinterpretation, delay and/or misdiagnosis. Such failures are avoidable by adequate clinic...

A case of severe acute encephalomyelitis associated with a serological diagnosis of both Mycoplasma pneumoniae and Legionella pneumophila infection is reported. Serological co-positivity between these two pathogens has been reported previously, and has, in general, been attributed to cross-reactivity. This is the first documented case of co-infection using more sensitive and specific serologica...

background: brucellosis is a zoonotic disease and its symptoms and appearances are not exclusive in human and its tradi­tional diagnosis is based on blood culture and serological methods. for more sensitive and specific detection, the pcr method is recommended. methods: one hundred four blood samples were gathered from suspicious patients with brucellosis different ages form ker­manshah, mazand...

Neonatal diagnosis of congenital toxoplasmosis is based on a combination serological and molecular tests. Maternal screening treatment differ according to national policies may impact the sensitivity diagnostic methods in infants at birth.

Diagnosis of Epstein-Barr virus (EBV) infection is based on clinical symptoms and serological markers, including the following: immunoglobulin G (IgG) and IgM antibodies to the viral capsid antigen (VCA), heterophile antibodies, and IgG antibodies to the EBV early antigen-diffuse (EA-D) and nuclear antigen (EBNA-1). The use of all five markers results in 32 possible serological patterns. As a r...

We previously derived a typology of schizophrenia from a latent class analysis of 447 first-contact non-affective functional psychotic patients from a defined catchment area. Here, using the same sample, we show that the three subtypes, 'neurodevelopmental' (Type A), 'paranoid' (Type B) and 'schizoaffective' (Type C) have different premorbid, phenomenological and treatment response characterist...

A positive serological diagnosis of amoebiasis could be made by immunofluorescence in 66 of 78 established cases, taking a serum titre of 16 or higher as diagnostic: at this level there were no false positives among 94 control sera. The test is simple and may be carried out on amoebic smears stored for several months in 2-octanol. The serological activity is largely confined to the IgG immunogl...
