Calcium is the most plentiful mineral in the human body. Ninety-nine percent is stored in the bones and teeth where it provides structure and functionality. The remaining 1% of the body's calcium is necessary for vascular contraction and vasodilation, muscle function, nerve transmission, intracellular signaling, and hormonal secretion. Serum calcium levels do not fluctuate in response to dietary intake. Bone tissue is the reservoir for calcium and helps to maintain concentrations in the blood, the muscle, and intercellular fluids. As humans age, the bone is constantly being laid down and reabsorbed. In growing children, bone formation exceeds that of bone resorption. In young and middle-aged adults, the bone formation and resorption is about equal. In older adults, especially in post-menopausal women, bone loss exceeds that of bone formation, which is why their risk for osteoporosis continues to increase as they age. The Corrected Calcium test aims to mathematically correct the measured total calcium for reduced albumin levels, especially in cases where total calcium is normal but there's suspected hypercalcemia with concurrent hypoalbuminemia.

Purpose of the test

The Corrected Calcium test aims to mathematically correct the measured total calcium for reduced albumin levels, especially in cases where total calcium is normal but there's suspected hypercalcemia with concurrent hypoalbuminemia.

Who Should Get Tested

Patients with suspected hypercalcemia and concurrent hypoalbuminemia, especially when the total calcium appears normal and an ionized calcium test cannot be obtained. It's important to note that the correction is not valid for certain groups, including those with chronic kidney disease, end-stage renal disease, or pregnant women

Blood Test Preparation Guidelines

Time of day

It is recommended to schedule your appointment for blood tests in the morning hours between 7:00-10:00.

Fasting

It is recommended to fast for approximately 12 hours before blood sampling. The last meal of the previous day should ideally be consumed around 6:00 p.m. On the day before the test, avoid heavy and fatty meals as well as alcohol.

Stay hydrated

Drinking water prior to testing can help with sample collection.

Other factors

Tests should not be performed after a sleepless night or intense physical activity. It is recommended to avoid exercise and stress immediately before blood collection and to not smoke. A short rest is recommended.

Medications and supplements:

Blood samples should be collected before the morning dose. Some drugs can interfere with test results. Consult with your doctor whether you can delay your dose because of lab tests.

Biotin supplements:

High doses of biotin supplements can affect test results, causing false elevation or reduction. It's recommended to avoid taking biotin for at least 72 hours before blood collection. If you are taking biotin, inform the personnel collecting the blood so that they can provide specific instructions.

Interpreting Test Results

The results will provide a corrected calcium value, which has been adjusted for albumin levels. It's crucial to understand that the formula used for correction hasn't been validated for pediatric subjects. If there are any discrepancies or doubts, confirmatory testing with ionized calcium is advised.
