What else can I help you with?
What are atypical antibodies?
these are the allo antibodies produced against the foreign cells in a transfused patient usually foun in patients with multiple transfusions
What happens in autoimmune hemolytic disorders?
The red blood cells are destroyed by antibodies produced by the patient's own body (autoantibodies).
A test used to detect anti-Rickettsia antibodies in a patient is the?
Indirect immunofluorescence assay (IFA) is commonly used to detect anti-Rickettsia antibodies in a patient. This test involves exposing the patient's serum to Rickettsia antigens and then using fluorescently labeled antibodies to detect any bound antibodies. Positive results indicate a past or current infection with Rickettsia bacteria.
Do lupus antibodies come and go?
Yes, lupus antibodies can *come and go*. Usually antibodies remain present in the patient, but they may be more difficult to find in a blood test. It is possible to have lupus and have negative antibodies.
What does diagnosis of yellow fever entail?
the examination of blood by various techniques in order to demonstrate either yellow fever viral antigens (the part of the virus that stimulates the patient's immune system to respond) or specific antibodies
A patient with rabies is given _____ to treat the infection?
hyperimmune specific antibodies
When the patient in art have undetectable virus do the elisa test detect the antibodys in blood?
When a patient has an undetectable viral load, it typically means that the virus is not present in significant amounts in the bloodstream, often due to effective treatment. However, the ELISA test detects antibodies produced by the immune system in response to the virus, not the virus itself. Therefore, even with an undetectable viral load, the ELISA test can still detect antibodies if the patient has been previously infected. It is important to note that the presence of antibodies indicates past exposure rather than current infection.
If igG is positive how can identify patient is infected or not?
If IgG antibodies are positive, it indicates that the patient has been exposed to the pathogen at some point in the past and has developed an immune response. However, it does not confirm an active infection, as IgG can persist long after the initial infection has resolved. To determine if a patient is currently infected, additional testing for IgM antibodies or direct detection of the pathogen (e.g., PCR or culture) is necessary. This combination of tests helps differentiate between past exposure and active infection.
what is cognitive-behavioral?
In cognitive-behavioral therapy, the therapist works with the patient to identify the thoughts that are causing distress, and employs behavioral therapy techniques to alter the resulting behavior.
What is elisa test igm and iga?
The ELISA test for IgM and IgA is a laboratory technique used to detect the presence of immunoglobulin M (IgM) and immunoglobulin A (IgA) antibodies in a patient's serum. IgM antibodies are typically produced early in an immune response, indicating a recent infection, while IgA antibodies are primarily found in mucosal areas and indicate local immune responses. This test is often used in diagnosing infections or autoimmune diseases, providing valuable information about the patient's immune status.
What type of immunity occurs when the patient is given direct antibodies?
artificial passive
When a patient has autoimmune hemolyic anemia antibodies destroy what?
Red blood cells
