An example report

Your vitamin D level is 28 nmol/L, below the report’s reference range of 50-250 nmol/L. This means your blood level is low. Vitamin D helps the body absorb calcium and supports bone strength, muscle function and immune health.

Vitamin D levels can be influenced by factors such as limited sunlight exposure, the season, skin covering, dietary intake and how the body absorbs or processes nutrients. Low levels are relatively common in the UK. Your corrected calcium and other measured vitamins and minerals were within range, which is reassuring, but they do not remove the significance of the low vitamin D result.

A single result does not explain why the level is low or indicate whether you have symptoms. If you have new or worrying symptoms, discuss them with your GP or NHS 111; call 999 in an emergency.

It would be worth discussing this result with your GP at a routine appointment. They can consider it alongside your medical history and advise whether any further assessment or vitamin D supplementation is appropriate, including the type and amount.

Your cholesterol pattern is not an emergency, but it is worth discussing with your GP at a routine appointment.

Total cholesterol is 5.62 mmol/L, LDL cholesterol is 3.72 mmol/L, and non-HDL cholesterol is 4.24 mmol/L - all above the report’s reference ranges. LDL and non-HDL cholesterol are the main cholesterol fractions linked with build-up in blood vessels over time. Your triglycerides and HDL cholesterol are within range, which is reassuring, but they do not completely offset the raised LDL and non-HDL results.

The level of concern depends on your wider cardiovascular risk, including factors such as age, blood pressure, smoking, diabetes, kidney health, family history and previous cardiovascular problems. This blood test alone cannot determine your overall risk. Your other results, including blood sugar markers, kidney function and inflammation markers, were reassuring according to the summary.

Factors that may influence cholesterol include dietary pattern, physical activity, body weight, smoking, alcohol, genetics and some health conditions or medicines. Your GP can interpret the result in context and explain whether any further assessment or management is appropriate. That’s a great question for your GP, who can consider your full medical history.

Yes. Your iron results form a consistent pattern of reduced iron stores and reduced iron availability.

Ferritin is low at 18 ug/L, suggesting that your stored iron is reduced. Serum iron is also below range at 11.2 umol/L, while transferrin saturation is low at 14.4%, meaning a relatively small proportion of the iron-transport protein is carrying iron. At the same time, total iron binding capacity and unsaturated iron binding capacity are raised. This can happen when the blood has more unused capacity to bind and transport iron.

Your full blood count is still within range, including haemoglobin and the red blood cell measurements. This means the iron changes have not been accompanied by the red-cell changes assessed in this test. Reduced iron stores can nevertheless be present before a full blood count becomes abnormal.

The results show what the pattern looks like, but they do not identify why your iron stores are low. Factors that may influence iron status include dietary intake, absorption, blood loss and some health conditions. Treatment or supplementation should not be started or changed based on this explanation alone.

Because several iron markers are outside range, it is worth discussing them with your GP at a routine appointment. They can consider your complete medical history and decide whether any further assessment is appropriate.
