Free STD Testing in Arlington, WA (Snohomish County)

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.

It does vary on a case-to-case basis. Insurance policies are often particular with the instances that they would be covering with their program. Some may cover severe accidents, some may even consider “orphan disease,” and yes, some may also cover the expenses for performing STD diagnostic tests. However, considering that your insurance provider will have to verify the person's identity availing of the program, STD testing laboratories that employ a minimal collection of patient information may not accept insurance policies to prioritize privacy over affordability.

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.

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.

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.
