Whole blood measurement of bilirubin: Bilirubin is routinely measured in infants before discharge to screen for hyperbilirubinemia (jaundice). Early detection prevents brain damage that may occur with high levels of bilirubin. I am currently investigating new methods to assess bilirubin with whole blood. This project compares whole blood bilirubin measurement to plasma bilirubin measurement to verify accuracy, efficiency and quality and assess factors which might interfere with the whole blood method. If successful, this will enable assessment using much smaller blood sample volumes and producing faster results at the point of care.
Biomarkers of preeclampsia: Early diagnosis of preeclampsia can potentially prevent some of the adverse outcomes associated with this disease. However, early diagnosis of this disease is currently limited by a lack of clinical tests in this area. There is increasing evidence that an enzyme that breaks down tryptophan, an amino acid essential in the diet, is involved in the development of preeclampsia. I am assessing the levels of tryptophan and its metabolites in maternal blood to see whether they can be used to identify patients with preeclampsia in the second trimester of pregnancy before preeclampsia would typically be diagnosed. The development of a new test to predict preeclampsia and its complications will help clinicians provide an accurate diagnosis early in pregnancy and modify patient care accordingly, thus allowing them to provide the best care for both mothers and babies.Grants
