High or low Complement C1q can be the result of a disease and the severity cannot be generalized, so there is no such thing as which is more serious.
Complement C1q is a component of complement C1, which is involved in the immune response, mediating inflammatory responses, and other processes. Complement is produced by the liver, and changes in its level are associated with disease. High or low levels may be associated with disease, and it is not possible to compare their severity, so there is no such thing as which is more severe.
High complement C1q can be seen in autoimmune diseases such as rheumatoid arthritis and gout, and in infectious diseases such as lung infections. Low complement C1q can be seen in conditions such as nephrotic syndrome, dry syndrome, systemic lupus erythematosus, and malnutrition.
Patients with high or low complement C1q are advised to go to the rheumatology and immunology department of the hospital in time to get a clear diagnosis under the guidance of the doctor, so as to avoid delaying the condition.
