Understanding the different testing methods is paramount in today’s ever-evolving healthcare landscape. Two of these methods stand out: dried blood spot testing (DBS) and venipuncture tests.   


Through this blog, we aim to shed light on the concept of DBS and its advantages, empowering seniors and healthcare practitioners with knowledge that can positively influence their health journeys.  


In this blog, we will learn about DBS and its processes, how it compares to traditional venipuncture tests and more. Let’s get started. 

Dried Blood Spot Testing: A Game Changer

Dried Blood Spot Testing (DBS) is a revolutionary method in healthcare that simplifies how we collect blood samples for testing. Unlike traditional venipuncture, which involves drawing blood from a vein, DBS uses a disposable lancet to create a tiny, virtually painless prick on the fingertip. This small drop of blood is then collected on a specialized filter paper, where it dries within hours. This innovative approach eliminates the need for bulky vials and needles, making the process far less intimidating and more convenient, especially for seniors

Advantages of DBS

Advantages of Dried Blood Spot Testing

1. Convenience

For seniors, convenience in healthcare is paramount. DBS collection offers just that. Patients can collect their blood samples in their homes, avoiding the hassle of traveling to a medical clinic. No more waiting rooms or long clinical visits. This method empowers individuals by putting control over their health in their own hands. 

2. Stability

DBS samples remain stable for extended periods, even at freezing temperatures. This stability is a game-changer for research testing. Unlike venipuncture samples, which must be used immediately or discarded, DBS samples can be preserved for future analysis, reducing waste and allowing for more comprehensive research.

3. Reduced Risk

Handling DBS is safer for laboratory personnel due to the natural drying process of the blood. Most infectious pathogens are destroyed during this drying phase, significantly lowering the risk of infection transmission. This added safety ensures that healthcare workers can focus on providing quality care without unnecessary health concerns. 


Dried Blood Spot Testing is a game-changer in healthcare, where precision and comfort matter most. Its simplified process, coupled with a range of benefits, ensures that seniors receive the best care without the inconvenience and risks associated with traditional methods. As a trusted healthcare center, EliteCare Health Centers are at the forefront of offering senior care services, including DBS testing, to elevate the healthcare experience for our senior community. 


Dried Blood Spot vs. Serum/Plasma for Hormone Detection

Regarding hormone detection, Dried Blood Spot (DBS) testing emerges as a powerful contender, offering distinct advantages, especially for seniors under hormone therapy.

Equivalence in Non-Topical Hormone Therapy

For those not undergoing topical hormone therapy, DBS provides results that are on par with traditional serum or plasma tests. This means that seniors can rely on DBS to accurately measure their hormone levels without the inconvenience of venipuncture. 

DBS results are just as precise, making it a suitable alternative for seniors seeking to monitor hormone levels for various health reasons. Whether tracking thyroid hormones for metabolic health or assessing estrogen levels for bone health, DBS holds its own.

Unique Benefits in Topical Hormone Therapy

However, where DBS truly shines is in the monitoring of patients undergoing topical hormone therapy. DBS offers a unique advantage for seniors receiving hormones through topical applications – linear dose response. 

In contrast to serum or plasma testing, which may not show proportional increases in hormone levels with topical applications, DBS reflects these changes accurately. This means doctors can fine-tune hormone therapy for seniors, ensuring they receive the precise dosage required for optimal health.  


The benefits are multifaceted. Firstly, it allows for safer and more effective hormone therapy, reducing the chances of over or under-dosing. Secondly, it minimizes the need for complex adjustments, making hormone therapy easier to manage for both the patient and their primary care physician 


Ultimately, DBS provides an insightful and efficient way to tailor treatment for seniors exploring hormone therapy options. It simplifies a complex aspect of healthcare, enhancing the overall experience at a health care clinic like EliteCare Health Centers. 

Disadvantages of Dried Blood Spot Testing

While Dried Blood Spot (DBS) testing offers significant advantages, it’s crucial to understand its limitations, especially for senior citizens relying on healthcare services. 

Disadvantages of Dried Blood Spot Testing

1. Differences in Analyte Representation

One limitation of DBS testing lies in its representation of analytes. Unlike traditional venipuncture, which measures the free fraction of hormones and other substances available to tissues, DBS quantifies the total amount, including what’s bound and inactive. For seniors seeking precise information about bioavailability, this can be a drawback.  


For instance, when monitoring thyroid function, DBS might show elevated total hormone levels due to binding proteins, even if the biologically active fraction remains stable. This distinction is vital for doctors making treatment decisions based on DBS results. 

2. Laboratory Preparation

Another challenge with DBS is the extensive preparation required in the laboratory. While it simplifies the collection process for patients with finger-prick sampling, the analysis demands intricate steps. Liquid Chromatography-Mass Spectrometry (LC-MS/MS) is often used for accurate measurement, requiring specialized equipment and expertise.  

For seniors undergoing routine physical exams, this could mean longer waiting times for results than more straightforward tests. Understanding the laboratory’s processing time is crucial when incorporating DBS into healthcare routines. 

3. Compliance and Contamination

Compliance issues can also arise, particularly with elderly patients. The finger-prick collection might be uncomfortable or challenging for those with dexterity issues or a fear of needles. Ensuring proper technique is vital for accurate results; seniors might require extra support.  


Additionally, contamination remains a concern. Seniors using topical hormone therapy must avoid accidental contamination during collection, which could skew results. Careful guidance from primary care centers like Elite Health and Wellness is essential.  


While DBS testing offers undeniable benefits, seniors must know its limitations. Open communication with healthcare providers during online doctor consultations and annual physical exams can help address these challenges effectively. Seniors must consider their unique healthcare needs when opting for DBS testing as part of their wellness journey. 

The Bottom Line

In closing, Dried Blood Spot (DBS) testing is valuable in modern healthcare, especially for our esteemed senior citizens. Its undeniable advantages offer a safer, more convenient, and accessible alternative to traditional venipuncture.  


The significance of understanding DBS cannot be overstated. For healthcare practitioners, embracing this method can enhance patient care while minimizing risks and inconveniences. It’s a leap toward a more patient-centric and efficient healthcare system.  


EliteCare Health Centers proudly offers DBS testing services, ensuring that seniors can access this innovative approach to diagnostics. As we journey into the future of healthcare, let us embrace the potential of DBS testing to provide seniors with the best possible care, making their health and wellness our top priority.
