The article reveals the need for a comprehensive laboratory assessment of testing antibodies to SARS-CoV-2. In progress it is focused on possible product studies false-positive results caused by presence human serum in that cross reacting with SARS-CoV-2 proteins. It concluded order reduce proportion false positive study require use confirmatory test.

Antibodies that reacted with plasma membranes of human eye muscle but showed no binding to plasma membranes of human skeletal muscle were identified in serum of patients with Graves' ophthalmopathy. Rabbit antithyroglobulin serum at a dilution of 1 X 10(-3) to 20 X 10(-3) had no effect on the binding of these antibodies to eye muscle membrane antigens. There was no correlation between antihuman...

serum, colostrum, and milk in an attempt to identify the immunoglobulin classes of neutralizing antibodies to the porcine enteric virus, transmissible gastroenteritis (TGE). The results of these absorption studies suggest that in colostrum and milk from sows experimentally (orally) or naturally infected with live virulent TGE virus, IgA is the predominant immunoglobulin class of TGE antibodies....

BACKGROUND Antibodies against tau protein indicate an interaction between the immune system and the neurocytoskeleton and therefore may reflect axonal injury in multiple sclerosis (MS). METHODOLOGY/PRINCIPAL FINDINGS The levels and avidities of anti-tau IgG antibodies were measured using ELISA in paired cerebrospinal fluid (CSF) and serum samples obtained from 49 MS patients and 47 controls. ...

A majority of patients with HBsAg-negative chronic active hepatitis (CAH) show considerably raised titres of serum antibodies against measles virus antigens. Since these patients often have high titers of antiactin specific antibodies against smooth muscle, and since actin is also incorporated into the measles virion during replication, we have examined whether there was any cross-reactivity be...

background: visceral leishmaniasis (vl) as one of the most important human parasitic disease is endemic in some parts of iran. several cases of vl have been reported recently in the ilam province. the current study aimed to assess the pre-sent status of human vl in the region. methods: a random cluster sampling method was used to collect 456 serums samples from the children up to 12 years of ag...

Hu5F9-G4 and AK117, novel cluster of differentiation 47 blockers, are used to treat solid tumors hematoma. Because is expressed on erythrocytes, treatment with monoclonal anti-cluster may interfere the results transfusion compatibility testing. This study analyzed interference AK117 Saline microcolumn gel methods were identify blood types patients. To screen irregular antibodies, salt water, in...
