#1
Which serological test is commonly used for the diagnosis of HIV?
ELISA
ExplanationEnzyme-linked immunosorbent assay (ELISA) is commonly used to detect HIV antibodies in the blood.
#2
In blood grouping, what does the 'AB' represent in the ABO system?
Agglutination Behavior
ExplanationIn blood grouping, 'AB' represents Agglutination Behavior, determining the presence or absence of antigens on red blood cells.
#3
In blood typing, what does the 'O' represent in the ABO system?
None of the above
ExplanationIn the ABO blood group system, the 'O' represents the absence of A or B antigens on the surface of red blood cells.
#4
Which blood group is considered the universal donor in the ABO blood group system?
O
ExplanationBlood group O is considered the universal donor in the ABO blood group system due to the absence of A or B antigens on red blood cells.
#5
What does the term 'serology' refer to in the context of laboratory medicine?
Study of blood serum
ExplanationIn laboratory medicine, 'serology' refers to the study of blood serum, including the detection of antibodies and antigens.
#6
What is the principle behind the RPR test used for syphilis diagnosis?
Agglutination
ExplanationThe RPR test operates on the principle of agglutination, where the clumping of particles indicates a positive result for syphilis.
#7
In blood typing, what does the 'Rh' stand for in the ABO-Rh system?
Rhesus Factor
ExplanationIn blood typing, 'Rh' refers to the Rhesus Factor, an antigen that determines the positive or negative aspect of the blood type.
#8
Which serological test is commonly used for the diagnosis of autoimmune diseases such as rheumatoid arthritis?
RF (Rheumatoid Factor) test
ExplanationThe RF (Rheumatoid Factor) test is commonly used to diagnose autoimmune diseases like rheumatoid arthritis by detecting specific antibodies.
#9
Which serological test is used to diagnose infectious mononucleosis?
Paul-Bunnell test
ExplanationThe Paul-Bunnell test is commonly used to diagnose infectious mononucleosis by detecting antibodies specific to the Epstein-Barr virus.
#10
Which serological test is employed to diagnose conditions related to the thyroid gland?
Thyroid Stimulating Hormone (TSH) test
ExplanationThe Thyroid Stimulating Hormone (TSH) test is commonly used to diagnose conditions related to the thyroid gland.
#11
Which test is used to detect the presence of antibodies in a patient's serum against their own red blood cells?
Coombs test
ExplanationThe Coombs test is employed to detect antibodies attacking the patient's own red blood cells.
#12
What is the primary purpose of the Western Blot technique in serology?
Detect specific proteins
ExplanationThe Western Blot technique is primarily used to detect and identify specific proteins in a sample.
#13
What is the main purpose of the complement fixation test?
Measuring complement activity
ExplanationThe complement fixation test is employed to measure the activity of the complement system in the blood.
#14
What is the principle behind the Paul-Bunnell test?
Agglutination
ExplanationThe Paul-Bunnell test operates on the principle of agglutination, detecting antibodies that cause clumping in the presence of infectious mononucleosis.
#15
Which serological test is used to detect antibodies against nuclear antigens in autoimmune diseases like lupus?
Immunofluorescence
ExplanationImmunofluorescence is commonly used to detect antibodies against nuclear antigens in autoimmune diseases such as lupus.
