{{Short description|Presence of a marker in blood}} '''Serostatus''' refers to the presence or absence of a serological marker in the blood. The presence of detectable levels of a specific marker within the serum is considered '''seropositivity''', while the absence of such levels is considered '''seronegativity'''.
==HIV/AIDS== The term serostatus is commonly used in HIV/AIDS prevention efforts. In the late 20th and early 21st centuries, social advocacy has emphasized the importance of learning one's HIV/AIDS serostatus in an effort to curtail the spread of the disease.<ref name=SAFE />
==Autoimmune disease== Researchers have investigated the effects of autoantibody serostatus on autoimmune disease presentation.<ref name=Neuromyelitis /><ref name=Rheumatoid /><ref name=Pancreatitis /> Study of seronegative patient populations has led to the identification of additional autoantibodies that could potentially help with diagnosis.<ref name=Novel /><ref name=Myasthenia />
