For any questions about Sexually Transmitted Diseases (STD) Triage, please contact info@firstderm.com DISCLAIMER: Sexually Transmitted Diseases (STD) triage is a medical information service. The medical information provided by our dermatologists is based on the information they are given by users and should not be regarded as a definitive diagnosis of any kind, but merely as complementary information to an initial internet search or other comparable investigation. Our physicians are specialists in dermatology and venereology. STD triage is not a diagnostic service, but can be used for guidance on what can be done in the event of a visual problem. Our doctors and STD triage cannot and do not replace a proper medical consultation. The service does not replace a face-to-face visit to your doctor, and should be treated as a complement to an internet search. Even if the dermatologist recommends a face-to-face visit, our customer surveys show that the relief of knowing what the problem could be is worth the cost of using service. This service is provided by iDoc24 Inc.
