C3A and C4A ELISA test in serum
C3A is one of the proteins formed by the cleavage of complement component 3. Traditionally thought to serve a strictly pro-inflammatory role, recent investigations have shown that C3a can also work against C5a to serve an anti-inflammatory role. In addition, migration and degranulation of neutrophils can be suppressed in the presence of C3a.

Serum-based tests : 2 ml SERUM. Centrifuge immediately after clotting. Keep at ambient temperature or 4°C for 24h. For longer periods, aliquot, freeze and ship frozen.
Soluble CD14 serum level (sCD14)
CD14 is expressed in monocytes/macrophages and has a critical role in the recognition of bacterial cell wall components (LPS). The extracellular part of CD14 can be cleaved and released in the plasma. There it will inactivate circulating LPS.

Methylation Cycle Polymorphisms (GFOL)
677C-T and 1298A-C are two SNP's in the gene coding for MTHFR (methylene tetrahydrofolate reductase).The T allele of 677C-T, and the C allele of 1298A-C are the “bad” alleles, corresponding to a low activity form of MTHFR. The low activity leads to accumulation of homocysteine, and low levels of folate.
