Laboratory tests are available to assess the function of the complement pathway and to measure levels of individual complement components. The pattern of complement abnormalities is often helpful in suggesting diagnostic possibilities. For example, when when total hemolytic complement, C3, and C4 are all decreased, one of the rheumatoid diseases is likely. In addition, complement levels in spinal and synovial fluid may provide helpful diagnostic clues.
实验室检查可用于评估补体途径的功能并测量各个补体成分的水平。补体异常模式通常有助于提示诊断可能性。例如，当总溶血补体、C3和C4均降低时，类风湿性疾病之一的可能性较大。此外，脊髓液和滑液中的补体水平可能提供有用的诊断线索。
