• Homocystine  – Blood – £77

High homocystine levels have been linked to more than 100 serious medical conditions including cardiovascular disease, heart attacks, strokes, Alzheimer’s disease and depression. Factors such as poor diet, smoking, alcohol and lack of exercise are thought to raise homocystine levels. Certain key nutrients, including vitamins B12, B6 and folic acid are necessary for homocystine metabolism. The Homocystine test is therefore suitable for those who are concerned about the risk of heart disease, and who have a family history of dementia.
