PCR (Polymerase Chain Reaction) testing has transformed the diagnosis of various medical conditions, including toenail fungus. This innovative technique enables us to identify fungal infections more accurately and quickly than traditional diagnostic methods. At Sole Focus, we have partnered with the private lab Dr. Toe® to offer PCR testing, to provide our patients with effective, accurate diagnosis.
Understanding PCR Testing
PCR is a powerful molecular biology method that amplifies specific DNA sequences. This technology allows for the detection of even tiny amounts of DNA from pathogens, including fungi. For toenail fungus, PCR identifies the genetic material of the fungus, resulting in an accurate diagnosis.
In contrast to conventional methods, which can rely on visual inspection or cultures taking weeks, PCR testing can provide results in as little as one to two days once the sample is received in the lab. This quick turnaround is useful for initiating prompt treatment, which is often important to those suffering from toenail fungal infections. Studies show that early intervention can lead to a 50% higher success rate in treatment outcomes.
How PCR Testing Works
The PCR testing process consists of several essential steps:
Sample Collection: The procedure begins with obtaining a sample. A foot care nurse uses a sterile instrument to remove a small piece of the affected toenail. This sample is then sent for testing.
DNA Extraction: The next step involves isolating DNA from the nail and any present fungal cells. This is crucial because it ensures that the targeted DNA is separated from other materials in the sample.
Amplification: The extracted DNA undergoes heating and cooling cycles that amplify specific DNA sequences associated with toenail fungus. This amplification is necessary for accurate detection.
Detection: Finally, the amplified DNA is analyzed to confirm the presence of fungal DNA. A positive result indicates an infection, allowing healthcare providers to recommend the appropriate treatment options.
Advantages of PCR Testing for Toenail Fungus
PCR testing presents several notable advantages over traditional diagnostic methods:
Speed: Results from PCR tests are available within two weeks, facilitating quicker diagnosis and treatment. Traditional cultures take up to four weeks.
Accuracy: PCR testing has a specificity of up to 99%, which minimizes the risk of false negatives and false positives, making it a dependable method for diagnosing toenail fungus. In contrast, the traditional culture method only has a specificity of about 55%.
Comprehensive Identification: PCR can simultaneously identify multiple fungi types, helping healthcare providers understand the specific cause of the infection. This thorough identification is crucial as it informs the choice of treatment.
Smaller Sample: The sample collection for PCR testing requires less infected nail compared to other diagnostic methods, offering a more comfortable experience for patients.
What to Expect During a PCR Test for Toenail Fungus at Sole Focus
When you visit Sole Focus for PCR testing, our professionals will ensure you are informed and comfortable throughout the process.
Sample Collection
Your visit begins with a consultation where a healthcare provider evaluates your symptoms and reviews your medical history. Once PCR testing is deemed necessary, the sample collection occurs in a sterile environment, aiming to make the procedure as easy as possible for you.
Results and Follow-Up
After sending the sample for testing, you can generally expect your results within two weeks. If your test is positive for toenail fungus, your healthcare provider will discuss the next steps for treatment. Options may include topical antifungals, oral medications, or photodisinfection, depending on the severity of the infection and your individual health considerations. These results can also be sent to your primary care provider, if you opt for prescription treatment.
The Importance of Accurate Diagnosis
Getting an accurate diagnosis of toenail fungus is vital for several reasons:
Avoiding Misdiagnosis: Conditions such as psoriasis, nail dystrophy, or even nail bed cancer can mimic toenail fungus. A PCR test ensures that you receive the correct diagnosis and appropriate treatment.
Preventing Further Spread: Fungal infections can spread to others. Early and accurate detection helps prevent transmission.
Improving Treatment Outcomes: Knowing the specific fungus causing the infection allows healthcare providers to create more effective treatment plans, improving your chances of recovery.

Taking Action for Healthy Nails
PCR testing is reshaping how we diagnose and treat toenail fungus. At Sole Focus, we prioritize patient care by employing the advanced testing method of PCR for the accurate diagnosis of toenail fungus.
If you suspect you have toenail fungus, reach out for a consultation. With quick and precise PCR testing, you can take the first step toward healthier, fungus-free nails. Understanding the science behind PCR testing empowers you to make informed choices about your treatment. Remember, timely action is key to effectively managing toenail fungus!
Note - PCR testing done through Sole Focus is not covered by MSP. There is a cost to the patient for this service. Samples are sent to a private lab, and patients wanting their results shared with their primary care provider should advise their nurse at the time of sample collection.
