Around 50% of fungal nail infections are misdiagnosed. If you've thrown everything and the bucket at that thick, yellow toenail of yours - it might not be what you think... ...the good news is Oxfordshire Chiropody & Podiatry offers a quick, painless in-clinic test to determine once and for all whether that dodgy-looking nail is fungal or not. The test is 97% specific for the most common type of fungal infection (dermatophytes), Dermatophytes are responsible for more than 90% of all toenail infections. Advantages of the Dermatophyte Test Strip (DTS)
Rapid results in just a few minutes, whilst you receive treatment
No need to send nail clippings to the laboratory and await results (minimum 6 week lead time, and 30% chance of false negative)
Positive result can be sent. to your GP practice to request oral anti-fungals, if appropriate
Scientifically proven to give accurate and reliable results
Can detect the presence of all the common dermatophytes in a small sample of nail
Cost-effective, as time not wasted on costly anti-fungal treatments
Immediate diagnosis - treat the infection without delay
Price £45.00 per test includes letter to GP
(plus appointment fee)
FAQ's How does it work? ​The Dermatophyte Test Strip (DTS) works by a process known as immune-chromotography, similar to that used in a pregnancy test. The DTS contains a monoclonal antibody (mAb) that specifically reacts with a polysaccharide that is present in the cell wall of dermatophytes. When an infected nail sample is added to the buffer solution the polysaccharide is released and picked up by the DTS. The fungal polysaccharide, if present, is absorbed into the test strip and then interacts with the mAb present in the strip. A pink line occurs in the test strip to confirm the test has worked whilst the appearance of a purple-brown line below it confirms the presence of dermatophytes in the sample. How accurate is the test? ​The DTS in published studies has been shown to have an accuracy of 97% - meaning you can be confident that the test will give results. How much sample is required? ​Due to the sensitivity of the test only a small amount of nail specimen is required. In work conducted to date, less than 1 gram of infected nail can predict the presence or absence of infection. What species can the strip detect? ​The test strip is able to rapidly detect the presence of different types of dermatophyte (T. rubrum, T. mentagrophytes [var. interdigitale], T. violaceum, T. tonsurans, Microsporum gypseum, M. canis and E. floccosum), including all the most commonly encountered species causing nail infection in the U.K. Is there reliable scientific evidence that the test really works? ​Yes, the DTS has undergone rigorous testing and to date a number of peer reviewed publications documenting its successful use have appeared in the British Journal of Dermatology and the Journal of Dermatology. ​ Can the test be used if I have been using anti-fungal treatments? Yes, unlike traditional mycology, the test is unaffected by any anti-fungal treatments which may be present in a nail sample. ​ Why should I bother diagnosing it, surely the podiatrist can tell by looking? Studies have shown that even experts (dermatologists & podiatrists) at very best can only be around 67% accurate by visual diagnosis meaning they still get 1 in 3 diagnoses wrong. Clinical guidelines and published papers repeatedly state it is good practice to establish a formal diagnosis before treating. Why?
Because around half of dystrophic (damaged) nails are not fungal.
Because one may risk treating (and charging) a patient for something they do not have.
