What is a calcium blood test?

The calcium blood test is a simple and popularly used test for determining one's "risk" for a variety of diseases.  A patient will typically have in-office phlebotomy to obtain blood, with lab technicians then taking the sample to check the level of calcium in the blood with point-of-care laboratory equipment.

Due to its accuracy and low cost, it is used extensively in clinical laboratories as a screening tool for numerous conditions related to metabolic disorders such as diabetes or hyperparathyroidism including but not limited to increased risk of bone fractures.

The 'calcium blood test is performed to determine the calcium concentration in the blood. The level of calcium varies with age, habitation location, pregnancy status, and medications being taken. Calcium plays an important role in muscular relaxation, nerve impulse transmission, regulating vital body activity, bone metabolism, and also enables teeth mineralization.

A calcium blood test checks for an imbalance in the levels of two types of calcium in the bloodstream. It measures the level of ionized and total serum calcium. If one exceeds the other, it can be a sign that there is a problem with absorbing or regulating all types of calcium.

In recent years new research has emerged suggesting that typical Western diets—which are high in sugar intake—both promote not only diabetes but also cardiovascular disease by causing chronic stress on our body’s ability to regulate glucose metabolism and to create insulin resistance, which triggers high levels of sugar-induced inflammation toxins (specifical fructose) that interfere with cellular metabolism and DNA signaling pathways.

A calcium blood test is a procedure that measures the amount of calcium in your blood. Depending on how high or low the levels are, this could mean many things. A high level of serum calcium indicates hypercalcemia. This usually occurs when there is excessive production of parathyroid hormone (PTH) by abnormal cells in your body, such as teratoma cancers and certain types of malignancies or polycythemia vera. The excess PTH increases renal clearance and resorption rates so you excrete more calcium than normal through urination, causing increased levels in the bloodstream. It may also occur with hyperparathyroidism (also called primary hyperparathyroidism), mineral bone disease.

The calcium blood test measures the amount of calcium in the blood and is used to screen for potential health problems such as kidney disease, intestinal bypass surgery, and pseudo fractures. A pseudo proximal fracture (also known as a false fracture) is a break on an X-ray that does not occur at or near a joint. Pseudo proximal fractures are more easily seen on bone films than plain films because they show calcification throughout the length of the bone where they usually do not appear on X-rays. Pseudo proximal fractures can be caused by any injury which pulls hard enough to allow quick formation of xanthotic new bone — 24 hours — just before healing occurs.

The estrogen hormone in girls and older women controls the level of calcium in their blood. Estrogen helps make more of the protein that keeps the body's calcium in the bones. It also tightens up muscle cells so they can't let go of this stored-up calcium when a bone is resorbed; instead, it stays around to keep bones strong. This means your child will need to eat about 2,500 mg per day - many times what she needs for bone health alone - just to maintain proper function!

High dietary intake early on encourages even stronger kidney lfts among 6-year-olds with type 1 diabetes. Testosterone levels also play a role because it regulates the production of an enzyme necessary for normal blood.

This blood test measures the level of calcium in someone's blood. The inverse correlation between bone density and fracture risk may have led to a common belief that increases in circulating levels of calcitriol, consistent with an increase in dietary intake, should be associated with a higher bone mineral content and a lower occurrence of fractures.

One way to measure calcium during a blood test is with the presence of parathyroid hormone (PTH) and vitamin D. If PTH levels are low, it may suggest the body does not need more calcium. Low or absent levels of parathyroid hormone (PTH) may indicate:

  • the bone marrow has been destroyed and is no longer synthesizing new red blood cells
  • high liver fibrosis interfering with the production of PTH by the thyroid gland
  • irreversible kidney damage or chronic renal failure

Lower than average levels for this exam would include goiter/low iodine intake, eating disorders such as anorexia nervosa, malabsorption such as celiac disease. Higher

The calcium blood test measures the level of calcium in the person's bloodstream. Certain heart or kidney problems can show up on this particular type of test, but it is more commonly used to detect hypercalcemia. Hypercalcemia is generally caused by cancer cells which are rapidly increasing in number and will often cause symptoms that include bone pain, nausea, vomiting, diarrhea, and confusion. It can also sometimes lead to arrhythmias or altered mental states.

A calcium blood test measures the level of calcium in the blood. This reveals how much protein you're breaking down to provide your tissues with extra energy because protein is broken down into its main component--glucose (or sugar).

Osteoporosis, osteopenia, or bone fracture prevention.

High levels of vitamin D deficiency.

Metabolic acidosis (not enough acid in bloodstream) .

Kidney failure.

Lactate buildup due to anaerobic metabolism. The body switches from aerobic metabolism for simple tasks to anaerobic metabolism when you run out of oxygen during intense exercise, causing lactate accumulation that can lead to fatigue.

20% Health Time | A Smarter Way to Build Workplace Wellbeing

Modern workplaces are increasingly recognising that employee health is not separate from performance—it is foundational to it. Long work hours, constant digital connectivity and rising stress levels have led to burnout, lifestyle diseases and declining engagement across industries. In this context, the concept of 20% Health Time has emerged as a forward-thinking approach to workplace wellness.

20% Health Time allows employees to dedicate a portion of their paid working hours specifically to activities that support physical, mental and preventive health. Rather than treating wellness as an after-hours responsibility, this model integrates health directly into the work culture.

 

What Is 20% Health Time?

20% Health Time is a structured workplace initiative where employees are encouraged or allowed to spend approximately one-fifth of their working time on health-related activities.

These activities may include:

  • physical exercise or movement breaks
     

  • mental wellness practices
     

  • health education sessions
     

  • preventive health screenings
     

  • stress management and recovery
     

The core idea is simple: healthier employees perform better and sustain productivity longer.

 

Why Traditional Wellness Programs Fall Short

Many organisations offer wellness benefits such as gym memberships or annual checkups. While valuable, these programs often fail because:

  • employees lack time to use them
     

  • wellness is seen as optional
     

  • participation remains low
     

  • benefits are disconnected from daily work
     

20% Health Time addresses these gaps by embedding wellness into regular work hours.

 

Why Health Time Matters in Today’s Workplace

Rising Lifestyle Disease Burden

Public health data shows increasing rates of:

  • diabetes
     

  • hypertension
     

  • obesity
     

  • mental health disorders
     

These conditions affect working-age adults and directly impact productivity and healthcare costs.

 

Burnout and Mental Fatigue

Constant pressure and lack of recovery time lead to:

  • chronic stress
     

  • disengagement
     

  • absenteeism
     

  • high attrition
     

Health Time creates space for recovery and resilience.

 

Sedentary Work Culture

Desk-bound work contributes to:

  • musculoskeletal problems
     

  • cardiovascular risk
     

  • low energy levels
     

Dedicated health time encourages movement and prevention.

 

How 20% Health Time Benefits Employees

Improved Physical Health

Regular movement and preventive care reduce long-term health risks.

 

Better Mental Wellbeing

Time for mindfulness, rest and stress management improves emotional balance.

 

Higher Energy and Focus

Healthy routines improve concentration and reduce fatigue.

 

Empowerment and Autonomy

Employees feel trusted to manage their wellbeing, increasing engagement.

 

How Employers Benefit from 20% Health Time

Increased Productivity

Healthy employees work more efficiently and make fewer errors.

Reduced Absenteeism

Preventive care lowers sick days and health-related disruptions.

 

Lower Healthcare Costs

Early detection and healthier habits reduce long-term medical expenses.

 

Stronger Employer Brand

Wellbeing-focused policies attract and retain top talent.

 

Sustainable Performance

Health Time supports long-term performance rather than short-term output.

 

Activities That Fit into 20% Health Time

Organisations can tailor activities based on workforce needs:

  • guided fitness or yoga sessions
     

  • walking or movement breaks
     

  • mental health workshops
     

  • preventive health checkups
     

  • nutrition education
     

  • stress and sleep management programs
     

Flexibility ensures inclusivity across roles and work models.

 

Evidence Supporting Health Time Initiatives

Workplace health research consistently shows that:

  • preventive health improves productivity
     

  • employee wellbeing programs reduce burnout
     

  • time invested in health yields measurable returns
     

According to WHO and workplace wellness studies, integrated health initiatives deliver better outcomes than standalone benefits.

 

Addressing Common Concerns

“Will this reduce working hours?”

No. Health Time improves efficiency, offsetting time spent through better performance.

 

“Is it suitable for high-pressure roles?”

Yes. High-stress roles benefit the most from structured recovery time.

 

“How do we measure impact?”

Metrics may include:

  • reduced absenteeism
     

  • improved engagement scores
     

  • lower healthcare claims
     

  • better retention
     

 

Implementing 20% Health Time Effectively

Successful implementation requires:

  • leadership support
     

  • clear guidelines
     

  • flexible scheduling
     

  • inclusive activity options
     

  • regular feedback
     

Health Time works best when seen as a cultural shift, not a perk.

 

Long-Term Impact on Organisational Health

Over time, organisations adopting Health Time observe:

  • healthier workforce
     

  • improved morale
     

  • reduced burnout
     

  • stronger team cohesion
     

  • sustainable growth
     

These benefits compound year after year.

 

Conclusion

20% Health Time represents a progressive shift in how organisations view employee wellbeing. By dedicating work time to health, companies acknowledge that productivity and wellbeing are deeply connected. Rather than reacting to burnout and illness, Health Time promotes prevention, balance and resilience. In a future where talent, performance and sustainability matter more than ever, integrating health into the workday is not a luxury—it is a strategic necessity.
