What happens after I get my results?

You'll receive detailed doctor notes in simple language explaining what your C1q levels mean for your immune system health and inflammation status. These notes include personalized recommendations about when to follow up with a specialist, what symptoms to watch for, and whether additional immune testing might be helpful. You'll also get the standard lab report and can track your C1q levels over time using our trends feature to monitor disease activity or treatment effectiveness.

When will I get my results?

Results for the Complement Component C1q test are typically available within 3-5 business days after your blood sample reaches the laboratory. You'll receive an email notification as soon as your results are ready to view in your secure online account, along with easy-to-understand doctor notes explaining what your levels mean.

Who should consider getting this test?

This test is important for people diagnosed with autoimmune diseases like lupus or vasculitis who need regular monitoring. It's also valuable if you experience recurrent severe swelling (angioedema), frequent infections suggesting immune deficiency, or unexplained inflammation. Your doctor may order this test if other complement tests show abnormalities or if they suspect certain immune-related conditions.

What symptoms indicate I may need this test?

Key symptoms include recurring episodes of severe facial or throat swelling, frequent infections that your body struggles to fight off, or symptoms of autoimmune diseases like joint pain, skin rashes, and persistent inflammation. You may also need this test if you have unexplained fatigue, fever, or if family members have autoimmune conditions or immune deficiencies.

What is Complement Component C1q and why does it matter?

C1q is a protein that acts like your immune system's early warning system, helping identify threats and trigger the proper immune response. It's the first component activated in the classical complement pathway, which is essential for clearing infections, removing damaged cells, and managing immune complexes. When C1q levels are abnormal, it can affect your body's ability to fight infections and properly regulate inflammation.

What does low Complement C1q mean?

Low C1q levels can indicate active autoimmune disease (especially lupus), immune complex disorders, or acquired angioedema. It may also be seen in certain cancers like lymphoma or carcinoma, or when C1q is being rapidly consumed due to ongoing inflammation or immune reactions. Low levels require medical evaluation to determine the underlying cause and appropriate treatment.

How often should I retest my Complement C1q levels?

If you have an autoimmune disease, your doctor will typically monitor C1q levels every 3-6 months to track disease activity and treatment response. During active flares or when adjusting medications, more frequent testing every 4-8 weeks may be necessary. Once your condition is stable, annual or semi-annual testing may be sufficient for ongoing monitoring.
