Anemia Metabolite Laboratory

We offer a CLIA-certified quantitative assay for methylmalonic acid, methylcitric acid, homocysteine and cystathionine.

We have also recently developed assays for the volatile fatty acids which are of great interest in the study of the microbiome particularly as to their presence as protective metabolites in the gut. We will continue to develop small molecule metabolite assays as requested by other researchers and we will offer these assays to the investigators at the Medical School and the wider community.
