Complement C3 and Complement C4
Metonym: C3 and C4
Essay sample: Serum
Essay description and associated physiology
Complement proteins act as enzymes that aid in the immunological and incendiary reaction. The complement system is an important mechanism for the demolition and removal of foreign materials. Serum complement levels are used to notice autoimmune disorders. C3 and C4 are the most often assayed complement proteins, along with total complement. Circularising C3 is synthesised in the liver and comprises 70% of the complement system, but cells in other tissues could as well create C3. C3 is an essential activating protein in the classic and alternate complement cascades. It is diminished in patients with immunological disorders, in whom it is consumed at an expanded rate. C4 is created primarily in the liver but could as well be created by monocytes, fibroblasts, and macrophages. C4 participates in the classic complement pathway.
What are the denotations?
Notice genetic insufficiencies
Assess immunological disorders
What does the essay result mean?
The normal reference value could be found on the lab report.
The result:
Normal C4 and diminished C3
Acute glomerulonephritis, C3 insufficiency
Diminished C4 and normal C3
Immune complex disorders, cryoglobulinemia,
Diminished C4 and diminished C3
Immune complex disorders
More information
Drugs that might increment C3 levels comprise cimetidine and cyclophosphamide.
Drugs that might reduce C3 levels comprise danazol and phenytoin.
Drugs that might increment C4 levels comprise cimetidine, cyclophosphamide, and danazol.
Drugs that might reduce C4 levels comprise dextran and penicillamine.
Complement, Total
Metonym: Total haemolytic complement, CH50, CH100
Essay sample: Serum
Essay description and associated physiology
The complement system comprises proteins that become activated and interact in a sequential cascade. The complement system is an important component of the body’s natural defence against allergic and immune reactions. It is activated by plasmin and is interrelated with the clotting and fibrinolytic systems. Activation of the complement system results in cell lysis, release of histamine, chemotaxis of white blood cells, expanded vascular permeability, and contraction of smooth musculus. The activation of this system could occasionally happen with uncontrolled self-destructive impacts on the body. In the serum complement assay, a patient’s serum is mixed with sheep red blood cells coated with antibodies. If complement is present in sufficient quantities, 50% of the red blood cells are lysed. Lower numbers of lysed cells are associated with diminished complement levels.
What are the denotations?
Support in the diagnosis of inherited angioedema
Assess complement activity in autoimmune disorders
Assess and supervise therapy for systemic lupus erythematosus (SLE)
Screen for complement insufficiency
What does the essay result mean?
The normal reference value could be found on the lab report.
The result is expanded in:
Acute-phase immune reaction (reaction to sudden expanded demand)
The result is diminished in:

Drugs that might increment total complement levels comprise cyclophosphamide and danazol.
Complete Blood Count
Metonym: CBC
Essay sample: Whole blood
Essay description and associated physiology
A complete blood count (CBC) is a group of essays used for basic screening purposes. It is probably the most widely ordered lab essay. Results provide the enumeration of the cellular elements of the blood, measurement of red blood cell indices, and determination of cell morphology by automation and evaluation of stained smears. The results could provide valuable diagnostic information regarding the overall wellness of the patient and the patient’s reaction to disease and treatment.
What are the denotations?
Notice haematological disorder, tumour, leukaemia, or immunologic abnormality
Determine the attendance of inherited haematological abnormality
Assess acknowledged or suspected anaemia and associated treatment
Supervise blood loss and reaction to blood replacement
Supervise the impacts of physical or emotional stress
Supervise fluid imbalances or treatment for fluid imbalances
Supervise haematological status during pregnancy
Supervise advancement of nonhematologic disorders, such as chronic obstructive pulmonary disease, malabsorption syndromes, cancer, and renal disease
Supervise reaction to chemotherapy and assess undesired reactions to drugs that might render blood dyscrasias
Provide screening as component of a general physical examination, particularly on admission to a wellness care facility or before surgery
What does the essay result mean?
The normal reference value could be found on the lab report.
The result:
Haemoglobin:

Elevated serum glucose or sodium levels might create elevated mean corpuscular volume values because of swelling of erythrocytes.
Recent transfusion history should be conceived when evaluating the CBC.
