Free STD Testing in Fernridge, MO (St. Louis 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.

Depending on the test being performed and the testing physician's targeted diseases, various types of samples can be requested from you. In some instances, a minuscule blood sample of a few milliliters will be collected, some might ask for a urine sample, and others may opt for a genital swab. Again, the sample being collected will depend on the test being conducted and the outcome that is being targeted for this particular procedure.

Similar to how other testing procedures behave, false-positive results are still evident even in STD testing. False-positive and even false-negative results are standard instances that showcase the imperfection of the test’s design – a factor that is present everywhere. However, despite certain inconsistencies in laboratory tests as such, physicians commonly use confirmatory tests that would often take another path entirely to arrive at the same conclusion – solidifying the initial test’s diagnosis while still ensuring that the second test is not following the inconsistencies of the first.

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.

A nucleic acid amplification test is a laboratory procedure that professionals often perform to make detecting a particular nucleic acid or gene being targeted easier and more convenient while still ensuring that the sample being collected is relatively minimal. Nucleic acid amplification tests, or NAATs, are usually the mainstay diagnostic test for most STDs due to their ability to detect the presence of pathogenic nucleic acids and genes in the patient sample with utmost accuracy and speed. NAATs depends on their ability to replicate the target RNA and DNA to create numerous copies – resulting in an increased convenience in the detection of the desired molecules instead of trying to either blindly look for one strand in a minuscule sample or collecting a large sample that could make the patient uncomfortable throughout the process. Although NAATs are often preferred for a more conclusive diagnosis of STDs, certain exceptions such as the availability of resources and instances of intermittent viral shedding could make NAATs less desirable than other tests. Fret not, however, as your physician is knowledgeable regarding these instances and would often request the best diagnostic procedure for your instances.
