What Results of Homocysteine mean?

Interpretations

  • Increased levels of homocysteine may be seen in vitamin B12 or folate deficiency. It should be confirmed by other tests for Vitamin B12 or folate 
  • Latest studies also suggest that raised homocysteine levels may be associated with increased risk of cardiovascular disease like heart attack or stroke 
  • In newborn testing, greatly increased concentrations of homocysteine in urine or blood means that it is quite likely the infant is suffering from homocystinuria
