Do all STDS show up in blood tests?
To test for chlamydia and gonorrhea, for instance, all that is required is a urine sample. For other STDs– like herpes, hepatitis, HIV and syphilis, a small blood sample is all the STD testing center requires. Many doctors' offices will test for STDs by doing an invasive (and sometimes painful) swab– we do not!
Depending on the test performed, most tests are completed and reported to your ordering healthcare provider within about 24 hours of receiving the sample for testing. Certain tests take several days to weeks. Results are sent directly to the ordering healthcare professional.
- Daily, weekly, or monthly testing must indicate the time interval and frequency of testing. Expire after 12 months from initial request, or 24 months for patients requiring lifetime testing. Physician's office will be notified to submit a new lab requisition when a standing order has expired.
- It usually takes 2 to 3 days to get the results. Sometimes the tests done from the swabs are not cultures, but are genetic tests to look for gonorrhea or chlamydia. The newest test is done with a urine sample rather than swabs.
- Blood tests that you will likely need to fast for include:
- blood glucose test.
- liver function test.
- cholesterol test.
- triglyceride level test.
- high-density lipoprotein (HDL) level test.
- low-density lipoprotein (LDL) level test.
- basic metabolic panel.
- renal function panel.
Blood tests can also give your doctor an idea of how well your organs are functioning and if they've been affected by cancer. Examples of blood tests used to diagnose cancer include: Complete blood count (CBC). This common blood test measures the amount of various types of blood cells in a sample of your blood.
- A typical routine blood test is the complete blood count, also called CBC, to count your red and white blood cells as well as measure your hemoglobin levels and other blood components. This test can uncover anemia, infection, and even cancer of the blood.
- A complete blood count (CBC) is a blood test used to evaluate your overall health and detect a wide range of disorders, including anemia, infection and leukemia. A complete blood count test measures several components and features of your blood, including: Hemoglobin, the oxygen-carrying protein in red blood cells.
- Even though these findings may suggest leukemia, the disease usually is not diagnosed without looking at a sample of bone marrow cells. Blood chemistry and coagulation tests: Blood chemistry tests measure the amounts of certain chemicals in the blood, but they are not used to diagnose leukemia.
Some rapid STD tests can give results within an hour. Other STD results make take up to 1-2 weeks to come in. This varies both by what test is used and what facilities your doctor's office has. Some doctors need to send out blood and urine samples to be tested.
- When symptoms do appear they may show up as early as two days after exposure, or take as long as one month. Syphilis: The chancre characteristic of the first stage of syphilis appears, on average, twenty-one days after infection, but may appear anytime between 10 to 90 days after exposure to the bacterium.
- You can eat or drink anything you'd like beforehand there's no need to fast. The other STD tests do not require any special preparation. If you are currently taking antibiotics, our doctors recommend waiting 1 week before getting tested for chlamydia, gonorrhea or syphilis.
- Generally, STD testing at a Planned Parenthood office in the US will carry a few different charges, including an exam fee and various lab fees. On average it'll cost you about $180* to test for the top four STD threats. However, this number can vary widely depending on where you are, your age and household income.
