Free STD Testing in Portland, OR (Multnomah County)

It is recommended to get tested for STDs if you have had unprotected sexual contact, multiple sexual partners, or if you are experiencing symptoms associated with STDs. Additionally, regular testing is recommended as part of routine sexual health care, even in the absence of symptoms, especially for individuals who are sexually active.

Standard STD testing can detect common sexually transmitted diseases such as HIV (Human Immunodeficiency Virus), chlamydia, gonorrhea, syphilis, herpes, and hepatitis B and C. Additional tests may be required for less common STDs or specific situations.

Although NAATs are well-known for their accuracy and sensitivity in detecting most STDs, it is also subject to certain inconsistencies, especially in the case of herpes infections. In Herpes, outbreaks often result in a relative increase in the patient’s viral load – leading to a timeline that usually has specific peaks at certain intervals instead of a consistent rise in viral load throughout. As such, sensitive tests such as NAATs are still unable to accurately diagnose herpes conditions, especially in cases where the patient has recently become asymptomatic and is currently between outbreaks. Other tests such as culture testing and type-specific virologic tests are often employed instead as a confirmatory diagnosis for the patient’s condition.

Similar to what was previously mentioned, herpes infections are known for their recurring tendencies – causing outbreaks now and then and thus causing an intermittent spike in the patient’s viral load for specific instances. In addition to that, other STDs also take time to proliferate and produce a sufficient viral load that could warrant a positive and, more importantly, accurate diagnosis and detection from the tests being administered. As such, detecting an STD a few days following exposure is often complex and unpredictable – leading physicians to follow a certain timeframe instead for testing STDs instead of blindly testing immediately following exposure. Physical exams, however, may supplement inaccurate laboratory diagnoses, especially in cases where the test is prone to false results.

It would vary depending on the condition that is being tested. STDs behave differently due to the varying pathogenicity of each STD’s causative organism. In some instances, you can get accurately tested as early as two weeks following exposure, while some are intermittently inaccurate due to its recurrence (much like in the case of herpes infections). To avoid this, be sure to discuss the intricacies of the test with your physician to understand whether a particular test could provide you with a conclusive diagnosis or if it still needs another confirmatory test to establish its premise.
