Which Method of STD Testing is Suitable for Me?

STD testing options in Union, MO

Every sexually active individual must protect their sexual health. Regular STD testing is the only way to care for your sexual health. However, sometimes it becomes confusing to select the right testing method as there are so many options available. For your convenience, we have gathered information about all available STD testing methods in Union, Missouri. Check them out to find out which option is suitable for you.

Private testing (Walk-in clinic)

This is one of the most popular ways to get tested for STDs today. These tests combine the best of both worlds for convenience and accuracy. You will order the test online at home, but you can walk into a professional lab testing center to get tested.

Doctor's office

Another option is to simply visit your regular clinic and talk to your doctor.

At-home STD testing

If you do not want to visit a testing center, then a great alternative is an at-home test kit. You don’t even need to leave your house to get tested for STDs this way, which makes it the most discreet option. Everything is done through email and snail mail.

Community health centers and community clinics

One last option for STD testing is a trip to a free clinic. If you go to a public STD-testing clinic, then you may get a free or discounted test, depending on your financial situation.

Are STD tests expensive in Union, MO?

It can be, but it does not necessarily have to be. What many people need to understand is that laboratory tests would most often than not be relatively pricey due to the technology that is being utilized behind these diagnostic techniques. However, opting for specific laboratories that offer more convenient testing procedures and discounted prices for diagnostic tests would help ensure that the price will not be much of an issue in providing you with the conclusive diagnosis of your condition. It might take some independent scanning to find the right testing center for you in the most acceptable price range, but it is not as impossible as many people make it out to be.

How long does it usually take for results to come back for an STD test in Union, MO?

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.

STD testing FAQs

Yes. Certain companies offer at-home testing kits wherein you are the one that will collect the specimens necessary for the test at the comfort of your own home. Sure, it might sometimes be subject to errors due to the potential contamination of the sample from collection to transportation, but it does offer a great deal of privacy and convenience for patients who would prefer to have their identities hidden in fear that their community will judge them.

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.

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.

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.

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.
