Which Method of STD Testing is Suitable for Me?

STD testing options in Knoxville, CA

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 Knoxville, California. 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 Knoxville, CA?

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 Knoxville, CA?

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

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.

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.

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 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 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.
