Which condition is diagnosed using the Hess test?

Correct option is B

Ans. (b) Sol. The Hess test is used to diagnose immune thrombocytopenic purpura (ITP). It helps in assessing platelet function by applying pressure to the skin and noting the formation of petechiae or bruises, which indicate thrombocytopenia.
Explanation of each option:
· (a) Disseminated intravascular coagulation – Incorrect. DIC is diagnosed with other tests such as PT, APTT, fibrinogen, and D-dimer levels, not the Hess test.
· (b) Immune thrombocytopenic purpura – Correct. The Hess test is used to assess ITP, a condition where the body’s immune system destroys platelets, leading to excessive bruising and bleeding.
· (c) Immunodeficiency syndrome – Incorrect. ITP is related to platelet count, not immunodeficiency, and is not diagnosed using the Hess test.
· (d) Chronic myeloid leukaemia – Incorrect. CML is diagnosed using blood tests and bone marrow biopsy, not the Hess test.
