Diagnosed with high levels of total complement (ch50) and c-reactive protein. What does that mean?
Inflammation: It means that you have some sort of inflammatory process going on inside of the body presently.
The complement system is an important effector mechanism of both humoral and innate immunity. Its functions are to promote phagocytosis of microbes, to stimulate inflammation, and to induce lysis of these organisms. The system is highly complex and comprised of over 50 effector and regulatory molecules. It is activated via one of three pathways: antibody, lectin, or by ...Read more
What to do if I have high levels of total complement (ch50) and c-reactive protein. What does that mean?
What means very high CH50 complement? Mine is 277 CAE, C3 and C4 normal. Ref ranges for lab are only greater than 60, but I read high could be pathologis
How do you feel?: The complement system is a chaotic system -- like the butterfly effect. Most-impacted by this is CH40. The CH50 test is subject to so many variables and artifacts that as long as you feel reasonably well and don't have some bizarre, mysterious illness, I wouldn't give an elevated value a second thought.
Nucleolar pattern on ANA 1:160 (up until now it has always been a centromere pattern at 1:1280) ccp at 28, complement ch50 at 63 just stopped methotr?
Not enough info: Anas must always be evaluated in the context of the entire clinical picture. You have given no information about the clinical problem and why you are taking methotrexate. The ANA patterns can change from test to test. The patterns only mean something if they fit the clinical symptoms.
Haven't been feeling well had lyme test done only band 18, 23 + ana was also + Complement, CH50 high. Google now scared I have cancer or something bad?
Could my severe vitamin d deficiency be the cause of my extremely high complement ch50 level? C3 and C4 are normal.
No: I'd ignore the high ch50 levels. This is a lab test that's hard to do and even harder to interpret.
Crp 2.73, ESR 22, ANA + speckled 1:40, complement ch50 is >60. 15 years of fatigue/malaise, headaches, ibs, aches and pains. Any correlation?
Chronic Lyme?: Have you been tested properly for chronic Lyme? Consider iSpot Lyme test, not conventional western blot.See 1 more doctor answer
Can you have a normal ch50 (total complement) blood test result, but still have low C3 and/or C4 levels? ...Or would low C3 or C4 show up on ch50 test?
CH50: Ch50 measures the terminal or classical pathway. Deficiency of this test requires further investigation. Low c3 and c4 levels suggest activation of the classical pathway. Low c3 and normal c4 levels suggest activation of the alternate pathway. C4 could be low with a normal ch50.See 1 more doctor answer
Basically no: It's more worrisome if it's low. Lab reference ranges are set so that maybe 5% of healthies fall outside on either end. Don't worry.
My complement Total (CH50) was elevated in July. Four months later, it was low (33). What can cause this?
It fluctuates: These levels vary tremendously with minor illness, even little viral stuff that you don't know you have. And reference ranges are set so that a few percent of healthies fall outside on either end. These labs are only small pieces in diagnostic puzzles.
What can cause the Sedimentation Rate-Westergren - 70; Complement C4, Serum - 53; Immunoglobulin M, Qn, Serum - 36; Complement, Total (Ch50) >63?
If complement c3, ch50, serum protein electrophoresis, and immunofixation suggest severe infection, why is CBC normal? I've never had blood culture.
Lab data: Without placing values in a clinical context with full history, exam and all data it is pointless to speculate. You need to be evaluated by a physician and if the one you are seeing cannot provide answers, get a second opinion. Try seeing an infectious diseases expert.
Probably normal.: These numbers are non specific. Unless you have a specific syndrome or symptoms these numbers really mean nothing.
I have normal levels of complement C2 and c4. C3 level is low. Ch50 is high-normal (57 u/ml)- (all are serum tests)-what are the possible causes?
Labwork: Proper medicine would be not to treat lab values but the patient. Based on the lab values you provided it is impossible to suggest any kind of diagnosis. We would need to know your presentation and other labwork that was done in order to help you sort it out.
Ana titer 1:80 - positive vitamin d - 17 complement, total >60 ch50 any idea what I might have? I am scared that it is cancer.
Rheumatologist said I have low bence-jones protein in urine. Complement c3, C4 are normal. Ch50 high. He said don't worry. Should I go to oncologist?
Yes: Go to see a hematologist/oncologist to evaluate further on the bence-jones protein.
Likely response to: Inflammation. Complement is one of the acute phase reactants that increase in response to inflammation in the body. All lab results need to be interpreted in the clinical context and the doctor who ordered the test is usually in the best position to do that.
Low complement: Low levels of complement are seen in persons with complement deficiency who are prone to recurrent infections as well as in certain autoimmune conditions, inherited angioedema conditions, and hives associated with vasculitis (inflammed blood vessels). These can all be serious. Collection of blood to measure complement is tricky and needs to be done right or low level could occur.
Mechanism for diseas: If you have a disease compatible with a complemented activated disorder, this test may be performed. It is an attempt to detect a mechanism for your disease condition.
