How is chlamydia tested, by blood or urine?

Question

A friend undergone an HIV test and the doctor suggested to test STD as well. They only got blood from him. The result said that he got chlamydia. I read some posting that chlamydia is tested thru urine sample. Can it also be tested using blood sample? If it is not, that means the clinic was cheating. I think since chlamydia is the most common STD, they just say a patient have chlamydia so they can sell to them medicine to take which means extra income to the clinic. Am i correct?

Answer 1

What Is It?

Chlamydia (pronounced: kluh-mid-ee-uh) is a sexually transmitted disease (STD) that is caused by bacteria called Chlamydia trachomatis. Although you may not have heard its name, chlamydia is one of the most common STDs. Because there often aren't any symptoms, though, lots of people can have chlamydia and not know it.

The bacteria can move from one person to another through sexual intercourse, and possibly through oral-genital contact. If someone touches bodily fluids that contain the bacteria and then touches his or her eye, a chlamydial eye infection is possible. Chlamydia also can be passed from a mother to her baby while the baby is being delivered. This can cause pneumonia and conjuntivitis, which can become very serious for the baby if it's not treated. You can't catch chlamydia from a towel, doorknob, or toilet seat.
How Does a Girl Know She Has It?

It can be difficult for a girl to know whether she has chlamydia because most girls don't have any symptoms. Chlamydia may cause an unusual vaginal discharge or pain during urination. Some girls with chlamydia also have pain in their lower abdomens, pain during sexual intercourse, or bleeding between menstrual periods. Sometimes a chlamydia infection can cause a mild fever, muscle aches, or headache.
How Does a Guy Know He Has It?

Like a girl, a guy can also have a difficult time telling whether he has chlamydia. Some guys may have a discharge from the tip of the penis (the urethra — where urine comes out), or experience itching or burning sensations around the penis. Rarely, the testicles may become swollen. Many times, a guy with chlamydia may have few or no symptoms, so he might not even know he has it.
When Do Symptoms Appear?

Someone who has contracted chlamydia may see symptoms a week later. In some people, the symptoms take up to 3 weeks to appear, and many people never develop any symptoms.
What Can Happen?

If left untreated in girls, chlamydia can cause an infection of the urethra (where urine comes out) and inflammation (swelling and soreness caused by the infection) of the cervix. It can also lead to pelvic inflammatory disease (PID), which is an infection of the uterus, ovaries, and/or fallopian tubes. PID can cause infertility and ectopic (tubal) pregnancies later in life.

If left untreated in guys, chlamydia can cause inflammation of the urethra and epididymis (the structure attached to the testicle that helps transport sperm).
How Is It Treated?

If you think you may have chlamydia or if you have had a partner who may have chlamydia, you need to see your family doctor, adolescent doctor, or gynecologist. Some local health clinics, such as Planned Parenthood, can also test and treat people for chlamydia.

The doctor will do an exam that may include swabbing the vagina or penis for secretions, which will then be analyzed. Sometimes doctors can diagnose chlamydia by testing a person's urine. Talk to your doctor about which test is best for you.

If you are diagnosed with chlamydia, the doctor will prescribe antibiotics, which should clear up the infection in 7 to 10 days. Anyone with whom you've had sex will also need to be tested and treated for chlamydia because that person may be infected but not have any symptoms. This includes any sexual partners in the last 2 months or your last sexual partner if it has been more than 2 months since your last sexual experience. It is very important that someone with a chlamydia infection abstain from having sex until they and their partner have been treated.

If a sexual partner has chlamydia, quick treatment will reduce his or her risk of complications and will lower your chances of being reinfected if you have sex with that partner again. (You can become infected with chlamydia again even after you have been treated because having chlamydia does not make you immune to it.)

It's better to prevent chlamydia than to treat it, and the only way to completely prevent the infection is to abstain from all types of sexual intercourse. If you do have sex, use a latex condom every time. This is the only birth control method that will help prevent chlamydia.

Answer 2

Chlamydia Blood Test

Answer 3

It wasn't detected at your office visit because you need to do a pelvic exam/cultures do diagnose it. It would not show up in a blood or urine test. They probably did basic labwork, anyway, and that doesn't show "specific" things unless they order a particular test. Bloodwork shows the amounts/types of either different types of blood cells (a CBC, or complete blood count), which can indicate anemia, infection/inflammation, etc (an infection would show in elevated white blood cells, but chlamydia would NOT cause that test to be abnormal since that infection is limited to the area that's infected rather than being systemic). A metabolic panel shows the amounts of different chemistries/electrolytes such as sodium, potassium, and also basic liver function enzymes, that sort of thing. Abnormal results are interpreted appropriately. A basic UA (urinalysis, or urine test) shows if there are any red blood cells, white blood cells, glucose, nitrites, etc in the urine. Most often they are used to specifically diagnose a bladder infection (UTI). It also would not show chlamydia. It's not that the doctor didn't do anything he was "supposed" to do. Did they ask about your sexual history at all? If they didn't know that an STD might be an option, that's probably why they didn't do a pap themselves. If it wasn't your gyn, they may not even do paps at all. That doctor did the standard tests you would do to find a cause of abdominal pain (such as a UTI).

Answer 5

The test is looking for evidence of infection by the bacterium Chlamydia trachomatis, the most common bacterial sexually transmitted disease (STD) in the United States.


How is the sample collected for testing?
Generally, your doctor will use a swab to take a cell sample or secretion from the infected area, such as the cervix, urethra, penis, anus, or throat. It may be possible to use a urine sample, but only if the particular lab where the sample is sent has a new, very sensitive molecular technology for this purpose.
done with a pap smear......

Answer 6

A urine test and a swab test collecting fluid from the penis or vagina is done to test for chlamydia. (Swab test is obtained by briefly placing a swab in the opening of the urethra at the tip of the penis; this causes discomfort and a burning sensation).

Are you sure they didn't collect a urine sample? I don't know what kind of STD clinic he went to, but most places wouldn't say someone has something when they don't. Maybe he should go to his doctor and get tested again.

Answer 7

.Diagnosis is made by isolating the Chlamydia bacteria in a culture, or by finding evidence of the bacteria's unique DNA in a urine or vaginal sample. On women, a speculum exam is performed by the doctor; a cervical sample is obtained and sent to the laboratory for analysis. In men, a smaller swab will be inserted in the meatus (or, newer studies are showing that a urine sample can be used instead.)
