NHS 111; Choose and Book; NHS Pathways; NHS Choices; In 2005 Peter Davies a former NHS head of communications set up a scheme enabling primary care trusts to provide directory-type information in the Yellow Pages directory. By setting up a national agreement with Yellow Pages he hoped to keep costs down and solve the problem of PCT patches ...
Lab Tests Online is a family of peer-reviewed non-profit web resources about clinical laboratory testing. [ 1 ] [ 2 ] The site provides information on clinical laboratory tests as well as conditions that are managed or diagnosed by lab tests . [ 3 ]
When a positive sample is added to the tubes, radioactively labeled (labeled with I125 or I131 radioisotopes) antibodies bind to the free epitopes of antigens and form an antigen-antibody complex. Unbound labeled antibodies are removed by a second reaction with a solid phase antigen.
The direct Coombs test is used to detect antibodies or complement proteins attached to the surface of red blood cells. To perform the test, a blood sample is taken and the red blood cells are washed (removing the patient's plasma and unbound antibodies from the red blood cells) and then incubated with anti-human globulin ("Coombs reagent").
Magnetic Immunoassay (MIA) is able to detect select molecules or pathogens through the use of a magnetically tagged antibody. Functioning in a way similar to that of an ELISA or Western Blot, a two-antibody binding process is used to determine concentrations of analytes.
A medical test is a medical procedure performed to detect, diagnose, or monitor diseases, disease processes, susceptibility, or to determine a course of treatment. The tests are classified by speciality field, conveying in which ward of a hospital or by which specialist doctor these tests are usually performed.
The antigens and antibodies combine by a process called agglutination. It is the fundamental reaction in the body by which the body is protected from complex foreign molecules, such as pathogens and their chemical toxins. In the blood, the antigens are specifically and with high affinity bound by antibodies to form an antigen-antibody complex.
