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.

National Dentist Day 2025

National Dentist Day: Best Oral Hygiene Tips Shared by Experts

Every year, on March 6th, National Dentist Day is celebrated to recognize the invaluable contributions of dentists in maintaining our oral health. This special day also serves as a reminder of the importance of good oral hygiene habits. Whether you're looking to improve your daily dental routine or seeking expert advice, we’ve compiled the best oral hygiene tips shared by dentists to help you achieve a healthy and confident smile.

1. Brush Properly, Not Just Regularly

Brushing twice a day is essential, but how you brush matters just as much as how often. Experts recommend using a soft-bristled toothbrush and fluoride toothpaste. Follow these steps for effective brushing:

  • Use a gentle, circular motion rather than scrubbing.

  • Brush for at least two minutes twice a day.

  • Ensure you clean all tooth surfaces, including the back molars and gum line.

2. Flossing is Non-Negotiable

Flossing removes food particles and plaque from between your teeth where your toothbrush can’t reach. Dentists suggest flossing at least once a day to prevent cavities and gum disease. If traditional flossing is difficult, consider using:

  • Water flossers

  • Interdental brushes

  • Floss picks

3. Rinse with Mouthwash for Extra Protection

Using an antibacterial mouthwash helps reduce plaque, prevents bad breath, and protects against gum disease. Look for a fluoride-based or alcohol-free mouthwash, especially if you have sensitive gums.

Tip: Rinse for 30 seconds after brushing and flossing for best results.

4. Eat a Tooth-Friendly Diet

What you eat significantly impacts your oral health. Dentists recommend incorporating the following foods into your diet:

  • Dairy products (milk, cheese, yogurt) to strengthen enamel.

  • Crunchy fruits and vegetables (apples, carrots) to naturally clean teeth.

  • Nuts and seeds for essential minerals like calcium and phosphorus.

  • Green tea for its antibacterial properties.

Avoid excessive consumption of sugary snacks, acidic beverages, and sticky candies, which can erode enamel and lead to cavities.

5. Stay Hydrated and Limit Sugary Drinks

Drinking plenty of water helps wash away food particles and bacteria, keeping your mouth fresh and clean. Limit soda, sports drinks, and coffee, as they can stain teeth and contribute to decay.

Pro Tip: If you drink sugary or acidic beverages, use a straw to minimize direct contact with your teeth.

6. Replace Your Toothbrush Regularly

A worn-out toothbrush is ineffective at cleaning your teeth. Dentists recommend replacing your toothbrush every 3-4 months or sooner if the bristles are frayed. Using an electric toothbrush can also improve plaque removal.

7. Schedule Regular Dental Checkups

No matter how diligent your oral hygiene routine is, visiting your dentist every six months is crucial for professional cleanings and early detection of dental issues. Regular checkups can help prevent cavities, gum disease, and even serious health conditions linked to poor oral health.

8. Protect Your Teeth While Playing Sports

If you engage in contact sports, wearing a custom-fitted mouthguard can protect your teeth from injuries and fractures. This simple preventive measure can save you from costly dental treatments.

9. Avoid Smoking and Tobacco Products

Smoking and tobacco use are major contributors to gum disease, tooth loss, and oral cancer. If you’re looking for another reason to quit, your oral health is a great motivation. Talk to your dentist about resources to help you quit.

10. Teach Kids Good Oral Hygiene Habits Early

Children should learn proper oral hygiene habits from a young age. Encourage them to:

  • Brush their teeth with fluoride toothpaste.

  • Floss regularly.

  • Visit the dentist every six months.

  • Avoid excessive sweets and sugary drinks.

Setting a strong foundation for oral health can prevent future dental issues and ensure a lifetime of healthy smiles.

Conclusion

This National Dentist Day, take the opportunity to improve your oral care routine by following these expert tips. Good oral hygiene isn’t just about having a bright smile—it’s also essential for overall health and well-being. Show appreciation for your dentist by prioritizing your dental health and scheduling your next checkup.
