https://www.medicalhealthtests.com/blood-tests/complement-ch50.html Would check C1q and do autoimmune work up including CBC, CMP, thyroid studies and antibodies, sed rate CRP, ANA, DS DNA for starters. Would also assess for possible infection ( including chronic prostatitis) and check CXR( chest /lungmass/lesions), possible thyroid ultrasound. Would repeat CH50 in 1 month to see if changed

Thrombin 14.5,PT 22.7,APTT 79 all prolonged. APTT mix not corrected, CH50-low @22, C4 norm, C3 low. SLE pt. Lab says other results prove it is not lupus anticoagulant. What else could cause this? C3 almost always low,C4 never low. Creatnine 1.4.
