The Association of Medical Laboratory Immunologists (AMLI) have developed a panel of antinuclear and anticytoplasmic antibody consensus sera that can be useful for enzyme immunoassay (EIA), Ouchterlony, and immunofluorescence assay methods. It was developed to assist in the evaluation of newly available EIA methods for the detection of autoantibodies. The panel of sera was evaluated in several ...

an electrocardiogram (ecg) leads physicians to diagnose many potentially life-threatening cardiac, metabolic, electrolyte, and toxicological conditions. this study was designed to evaluate the competency of emergency medicine residents (emrs) in comparison with cardiologists in the interpretation of ecg when an interpretation checklist is used. this clinical trial was done in the emergency ward...

Background: Fetal electrocardiography is a developing field that provides valuable information on the fetal health during pregnancy. By early diagnosis and treatment of fetal heart problems, more survival chance is given to the infant.Objective: Here, we extract fetal ECG from maternal abdominal recordings and detect R-peaks in order to recognize fetal heart rate. On the next step, we find a be...
