Free STD Testing in Preston, AL (Marshall County)

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.

Considering that a wide variety of testing kits and laboratory procedures can be performed to determine conclusively whether you have a particular STD or not, the time that it will take for your results to return will also be subject to the same inconsistency. Although there are specific laboratories that could produce your results even by the end of the day (albeit, it is extremely rare for institutions to do so unless necessary), most would often take a few days to a week before the results are either delivered or posted online through your secure personal profile (in the case of online transactions). In addition to that, the capability of the laboratory performing the test may also contribute to the overall timeframe of result delivery – causing delays in cases where there are several requests or understaffed to provide expedited results.

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.

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.

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.
