About Blood & Heart Conversions

This category focuses on haematology and iron studies — the tests behind anaemia work-ups and blood counts. It includes a full iron panel (serum iron, TIBC, transferrin saturation and ferritin) plus the B-vitamins and markers tied to anaemia and cardiovascular risk (vitamin B12, folate and homocysteine), and haemoglobin conversion between g/dL and mmol/L.

Iron studies are a good example of why context beats a single value: ferritin is an acute-phase reactant that rises with inflammation, TIBC moves in the opposite direction to iron, and a "normal" B12 can still sit alongside a true deficiency picked up by methylmalonic acid. The dedicated pages here carry those nuances and the sex-specific reference ranges, so a converted result can be read the way a clinician would read it.

Frequently Asked Questions

Common questions about blood & heart lab unit conversions.

Which tests make up an iron panel?

Typically serum iron, total iron-binding capacity (TIBC), transferrin saturation (calculated from the two) and ferritin. Read together they distinguish iron deficiency from other causes of anaemia better than any single value.

Why can ferritin be normal or high in iron deficiency?

Ferritin is an acute-phase reactant, so infection, inflammation or liver disease can raise it even when iron stores are low. That is why it is interpreted alongside the rest of the iron panel and clinical context.

How are these blood values converted between units?

Iron and TIBC convert between µg/dL and µmol/L with a factor of 0.179, ferritin is 1:1 between ng/mL and µg/L, and B12 and folate use their own molecular-weight factors. Each dedicated page shows the exact conversion.
