Private Folate Blood Test
Because your health matters
Understand your Vitamin B9 status with a private Folate Blood Test. This quick test assesses whether your folate levels are within a healthy range and can help identify deficiency-related symptoms such as fatigue, ulcers or anaemia. Useful for anyone with dietary restrictions, absorption issues or increased folate needs.
What a Folate Blood Test checks
Folate (vitamin B9) is essential for healthy cell function, red blood cell production, DNA formation and tissue growth. It’s especially important during pregnancy, when the body needs higher levels to support foetal development.
Most people get enough folate from food, but deficiencies can occur if you follow a restricted diet, struggle to absorb vitamins or have increased needs (such as during pregnancy). Low folate can lead to symptoms like extreme fatigue, pins and needles, ulcers, diarrhoea and folate deficiency anaemia.
If you’re concerned about your folate levels, a private folate blood test is a quick and accurate way to check whether your levels are within a healthy range and whether you may need supplements or further investigation.
