Clinicians use this ratio when albumin is high or low to better understand total calcium. It can help assess symptoms like muscle cramps, tingling, or kidney stone history, and guide whether to check PTH, vitamin D, magnesium, or ionized calcium. It’s also useful for tracking trends over time alongside hydration and health changes. You can test this marker with Aniva across Germany and Finland.

High: Suggests calcium is higher relative to albumin. This can appear with dehydration, high calcium or vitamin D intake, some diuretics, or parathyroid overactivity. Consider hydration, reviewing medicines and supplements, and confirming with ionized calcium, PTH, and vitamin D.
Low: Suggests calcium is lower relative to albumin. This may relate to low vitamin D or intake, kidney issues, or low magnesium. Discuss symptoms and consider checking ionized calcium and related nutrients, especially if albumin is very low.
Common factors that can shift results include dehydration or overhydration, pregnancy, recent illness, and strenuous exercise. Supplements (calcium, vitamin D), antacids, thiazide diuretics, and lithium can raise or lower calcium. Low albumin from liver, kidney, or inflammatory conditions can make total calcium look low even when ionized calcium is normal. Tight tourniquet use or delaying sample processing can also skew values.
Special situations: if albumin is far from normal, or symptoms don’t match results, confirm with ionized calcium or a corrected calcium calculation and consider repeat testing.
What does the calcium/albumin ratio show? It compares calcium with albumin to add context to total calcium, especially when albumin is high or low.
Do I need to fast for this test? No. Fasting isn’t required; drinking water is fine unless your clinician advises otherwise.
What can affect my results? Calcium or vitamin D supplements, thiazide diuretics, lithium, dehydration, pregnancy, recent illness, and heavy exercise can shift values.
How often should I test it? Usually when calcium or albumin is out of range, or to track a change. Your clinician may repeat in weeks or months based on context.
How long do results take? Most labs report results within 1–3 business days.
What should I discuss with my clinician? Your symptoms, all medicines and supplements, hydration status, and whether to confirm with ionized calcium, PTH, or vitamin D tests.
