The provided UK guidelines and PubMed literature do not specify the essential laboratory tests for confirming a diagnosis of common variable immunodeficiency (CVID) in a patient presenting with recurrent infections.
The available PubMed literature discusses aspects of common variable immunodeficiency such as cutaneous granulomas [ Aghamohammadi et al. 2010 ] and an approach to CVID in horses [ Mullen & Felippe 2024 ], but does not detail human diagnostic criteria or specific laboratory tests.
The UK guidelines provided cover coeliac disease NICE NG20, vitamin B12 deficiency NICE NG239, and bacterial meningitis NICE NG240, which are not directly related to the diagnostic laboratory tests for CVID.
