On-the-spot blood vitamin D testing in pharmacies and dental clinics.

What is the role of vitamin D?

Vitamin D supports calcium absorption, bone mineralization, muscle, and immune function. Low levels of vitamin D raise the risk of rickets in children and osteomalacia in adults. Very high levels, usually from supplements, can contribute to hypercalcemia.

Vitamin D measurement is used in dentistry. Adequate vitamin D levels may support stronger osseointegration, which can contribute to better dental implant stability. When vitamin D is lacking, the bone’s ability to remodel around the implant may be reduced, potentially delaying healing and raising the chance of complications.

What factors influence vitamin D levels?

One of the factors influencing vitamin D levels is sun exposure, as well as adjustments to sun exposure such as sunscreen usage. Another factor is diet - fatty fish, fish liver oils, dairy products, and eggs are rich in vitamin D. Of course, individual factors, such as skin color, body fat composition, and certain health conditions and medications, affect vitamin D levels.

Why vitamin D testing matters in pharmacies and in dental clinics?

Vitamin D testing in both pharmacies and dental clinics is important because it helps detect deficiencies early, allowing pharmacists to guide supplementation and dentists to optimize bone healing and implant outcomes.

The value of offering vitamin D testing in pharmacies and dental clinics:

• Strengthens their role as community health and wellness hubs.
• Helps identify at-risk groups needing vitamin D assessment.
• Provides quick and convenient vitamin D status checks for customers.
• Enables personalized supplements, advice, or referrals when necessary.

How is vitamin D measured?

• Sample: Blood.
• Analyte: 25(OH)D.
• Units: ng/mL.

Interpretation: Always follow the instructions for use (IFU) provided to your pharmacy or dental clinic with the device and a test kit.

Vitamin D testing with Igloo Reader Pro

Vitamin D can be measured rapidly from a small capillary blood sample on the Igloo Reader Pro in a pharmacy or in a dental clinic or any other health-related point-of-care business. Results can be recorded and tracked in the app and combined with other markers where relevant.

Benefits of vitamin D testing with the Igloo Reader Pro for pharmacies and dental clinics:

• Deliver fast, accurate vitamin D results at the point-of-care.
• Expand preventive health services offered on-site.
• Support early detection of vitamin D deficiency or excess.
• Seamlessly integrate testing into daily pharmacy and dental clinic workflows.

What are normal vitamin D values?

In adults, normal ranges are typically 30 to 50 ng/mL, though slight variations may exist depending on the laboratory or testing device.

What are low and high vitamin D levels?

• Very low level: <12 ng/mL, suggests vitamin D deficiency.
• Low level: 12 - 20 ng/mL.
• Below optimal: 20 - 30 ng/mL.
• Very high level: >50 ng/mL, potential risks rise with excessive supplementation.

It is important to underline that many labs have slightly different guidelines and reference intervals, which should be taken into consideration while looking at the clinical context. The normal ranges may differ depending on age, sex, and other parameters.

In cases of low vitamin D, pharmacies can provide guidance on potential vitamin D-rich dietary sources, commonly recommended supplements, and lifestyle adjustments, while always referring customers to a clinician for personalized evaluation and supplementation advice.

Why pharmacies and dental clinics should offer vitamin D testing?

Utilizing the Igloo Reader Pro for vitamin D testing enables pharmacies and dental clinics to offer rapid, reliable assessments that improve early detection and management of vitamin D imbalances. This enhances patient care, strengthens community health engagement, and opens new avenues for service growth through personalized testing and supplementation guidance.
