What Is The Adjusted Calcium Test For?

Calcium binds to proteins in the blood, especially albumin. So when albumin levels are low, calcium levels will be measured as low, even though the level of unbound calcium in the blood may be normal.

A corrected calcium result aims to compensate for the serum albumin level and indicates the true calcium level.

What if Adjusted Calcium Results Are High?

High calcium levels are known as hypercalcaemia, meaning there is too much calcium in the blood. There are a wide range of possible causes of raised calcium, and it can be linked to a number of health issues. This finding is commonly reviewed further to clarify the underlying cause.

A high calcium result is generally treated as clinically significant. There are multiple potential causes, and different causes are explored in different ways.

When the calcium level is above 3, this is often treated as a more urgent result, as urgent treatment may be required.

What if Adjusted Calcium Results Are Low?

Low calcium can have multiple causes, including dietary insufficiency, gastrointestinal problems, kidney problems, or endocrine problems such as hypoparathyroidism.

This finding is often reviewed further to clarify the cause.

Can Adjusted Calcium levels vary through the day?

Yes. Your calcium levels can fluctuate throughout the day and may be influenced by factors such as diet, medication, time of day, and even your menstrual cycle. Hence, there might be a need for regular monitoring if you're susceptible to conditions impacting calcium metabolism.

How reliable is the Adjusted Calcium test?

The Adjusted Calcium test kit from Vitall is a highly reliable tool in establishing calcium levels in your body. The analysis of the samples is conducted in a UKAS accredited lab, ensuring accuracy and integrity of the results.

Are there any specific preparations needed before taking the Adjusted Calcium test?

The Adjusted Calcium test requires no specific preparations. However, make sure you follow the step-by-step guide provided with the kit for sample collection. Also, always consult with your healthcare provider before discontinuing any regular medication.

How are the results of the Adjusted Calcium test interpreted?

Once your blood sample is analysed at our lab, you will receive your results via your private online dashboard. Increased levels from the Adjusted Calcium test could imply potential conditions like hyperparathyroidism or certain types of cancer whereas low levels might indicate conditions like Vitamin D deficiency or renal failure. The results should be discussed with a healthcare provider for definitive interpretation, diagnosis, or treatment so other symptoms and clinical history can be considered.

What should I do if my Adjusted Calcium test results are normal?

If your Adjusted Calcium test results are normal, this means your calcium levels are within the expected range. However, if symptoms persist, it's always good practice to speak to a healthcare provider for further investigation.

What is the Adjusted Calcium test?

The Adjusted Calcium, or Corrected Calcium test, is a diagnostic tool used to measure the level of calcium in your blood that is not bound to proteins, providing a more accurate picture of your body's available calcium. It can be vital in diagnosing and monitoring a range of health conditions, such as bone disorders, kidney disease, or parathyroid disorders.

What symptoms may warrant an Adjusted Calcium test?

Symptoms that may warrant an Adjusted Calcium Test include chronic fatigue, muscle cramps or spasms, frequent bone fractures or bone pain, depression or confusion, abnormal heart rhythms, and numbness or tingling in the face, hands, and feet.

How does the Adjusted Calcium test work?

The Adjusted Calcium test is a blood test conducted by yourself at home using a finger-prick blood sample collection method. The kit provided by Vitall allows you to collect a small blood sample, which is then sent to a UKAS licensed laboratory for analysis.

How do I use the Adjusted Calcium test?

The Adjusted Calcium Test kit comes with clear, simple instructions. You will need to clean your finger, use the lancet provided to prick your finger, and collect a small blood sample in the tube provided. It’s essential to keep the tube upright and mix it gently after sample collection. After that, you simply send it to the lab in the prepaid package. Your results will then be reported securely online.
