One can interpret the CH50 value along with the individual's complement factor values to help determine the etiology. For example, if and individual has normal C3/C4 values but a decreased CH50, that can indicate a terminal complement pathway deficiency while if one has low C3 and CH50 values that can indicate an autoimmune condition such as ...
Diagnosis usually consists of medical evaluation in addition to laboratory testing. Laboratory evaluation includes complement studies, in which typical cases demonstrate low C4 levels, low C1q levels, and normal C3 levels. [3] Determining the etiology, or cause, of acquired angioedema is often helpful in providing appropriate management of AAE.
The size of either C4A or C4B gene can be 21 kb (long, L) or 14.6 kb (short, S). Also, the long C4 gene uniquely contains a retrovirus HERV-K(C4) in its intron 9 that imposes transcription of an extra 6.36 kb, hence the “longer” string of gene. [2] [14] Thus, C4 genes have a complex pattern of variation in gene size, copy number, and ...

Reference ranges (reference intervals) for blood tests are sets of values used by a health professional to interpret a set of medical test results from blood samples. Reference ranges for blood tests are studied within the field of clinical chemistry (also known as "clinical biochemistry", "chemical pathology" or "pure blood chemistry"), the ...
[13] [14] Varying haplotypes of this gene cluster exist, such that individuals may have 1, 2, or 3 copies of this gene. [5] Each copy of the gene, due to five adjacent nucleotide substitutions cause four amino acid changes and immunological subfunctionalization, [ 15 ] can be of one of two types: C4A and C4B . [ 16 ]
The C1q domain is a conserved protein domain. C1q is a subunit of the C1 enzyme complex that activates the serum complement system.C1q comprises 6 A, 6 B and 6 C chains.These share the same topology, each possessing a small, globular N-terminal domain, a collagen-like Gly/Pro-rich central region, and a conserved C-terminal region, the C1q domain.
