Some infections, such as <strong><a href=\"https:\/\/www.ashasexualhealth.org\/get-tested\/\">chlamydia or gonorrhea<\/a>,<\/strong> can have no noticeable symptoms, but can lead to other health issues like pelvic inflammatory disease (PID), fertility issues, chronic pain, or organ damage.\u00a0<\/p>\n\n\n\n<p>The common confusion is that STD screenings are included in a full checkup that includes routine blood work or a single type of blood or urine sample that was taken. STD screenings aren&#8217;t done during routine blood tests or urinalysis unless specifically ordered. In addition, STD test types differ in which infections they can detect, so there is no single best STD test type. A single blood test cannot check for all STDs, as a single urine test cannot. To have a chance of detecting any infection, urine and blood tests must be done together.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-std-blood-tests-work\"><strong>How STD Blood Tests Work<\/strong><\/h2>\n\n\n\n<p>STD blood tests can only detect certain STDs because those STDs contain the genetic material of viruses that enter the bloodstream and are not localized to the genital area. They can also be identified by the body&#8217;s immune response, in which antibodies are produced.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-stds-commonly-detected-with-blood-tests\"><strong>STDs Commonly Detected with Blood Tests<\/strong><\/h3>\n\n\n\n<p>Which STD tests use blood include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>HIV<\/li>\n\n\n\n<li>Syphilis<\/li>\n\n\n\n<li>Hepatitis B &amp; C<\/li>\n\n\n\n<li>Herpes (type-specific antibodies)<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-accuracy-and-timing-considerations\"><strong>Accuracy and Timing Considerations<\/strong><\/h3>\n\n\n\n<p>With blood tests, there can be a delay between exposure and when the antibodies become detectable, which can range from a few weeks to months. Testing too soon can result in a false negative, but continuing follow-up screenings should produce a true negative or positive result. The professionals at ARCpoint Labs of Martinez, CA, can determine whether results are true positives or negatives based on the infection&#8217;s detection timeframe.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-how-std-urine-tests-work\"><strong>How STD Urine Tests Work<\/strong><\/h2>\n\n\n\n<p>STD urine tests detect bacteria causing certain STDs that affect the urethra. The DNA from these types of bacteria is shed into the urine, making detection in urine STD tests effective.&nbsp;<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-stds-commonly-detected-with-urine-tests\"><strong>STDs Commonly Detected with Urine Tests<\/strong><\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Chlamydia<\/li>\n\n\n\n<li>Gonorrhea<\/li>\n\n\n\n<li>Trichomoniasis<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-timing-and-accuracy\"><strong>Timing and Accuracy<\/strong><\/h3>\n\n\n\n<p>As with blood tests, testing too early can lead to false negatives. However, the timeframe from exposure to detection is shorter. The best testing time after exposure, when doing STD urine tests, is about one to two weeks if there are no symptoms. If symptoms appear, get tested immediately, regardless of when the exposure occurred. Both blood and urine STD testing accuracy is about the same, at 95 to 99%. Male patients usually prefer a urine test for STD accuracy over uncomfortable genital swabs.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-why-both-tests-may-be-recommended\"><strong>Why Both Tests May Be Recommended<\/strong><\/h2>\n\n\n\n<p>Because STD testing methods comparison between blood and urine differ in the types of STDs they detect, both tests may be recommended as a comprehensive screening to eliminate any possibilities of STDs.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-comprehensive-detection\"><strong>Comprehensive Detection<\/strong><\/h3>\n\n\n\n<p>Combining tests increases overall accuracy by systematically checking all STD possibilities. The best cases where dual testing is important are:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>If there is unprotected sexual activity<\/li>\n\n\n\n<li>Before engaging in sexual activity with a new partner<\/li>\n\n\n\n<li>Pregnancy<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"h-choosing-the-right-test-for-you\"><strong>Choosing the Right Test for You<\/strong><\/h3>\n\n\n\n<p>ARCpoint Labs of Martinez, CA, helps determine the best testing approach based on your symptoms or lack thereof, exposure history, and risk factors.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-schedule-your-confidential-std-testing-today\"><strong>Schedule Your Confidential STD Testing Today<\/strong><\/h2>\n\n\n\n<p>You can trust ARCpoint Labs of Martinez, CA, for privacy, convenience, and professional care with an STD panel test.
