LGV is a sexually transmitted disease caused by the Chlamydia trachomatis bacteria. Diagnosis of LGV involves a combination of laboratory testing, physical examination and patient history.
Laboratory testing is typically the first step in diagnosing LGV. A sample of cells taken from the infected area may be tested for the presence of the bacteria. This sample may be taken from a genital lesion, rectal swab, or urine test. The sample will be examined for the presence of the bacteria under a microscope. If the bacteria is present, then the diagnosis of LGV is made.
Additionally, a blood test may be used to detect antibodies associated with the bacteria. This test can help confirm the diagnosis of LGV in patients who have a positive urine or swab test.
Physical examination is also important in diagnosing LGV. During the physical exam, the doctor will look for any signs or symptoms associated with LGV. These may include swollen lymph nodes, genital sores, or discharge from the genitals.
Finally, a patient's medical history is important in diagnosing LGV. The doctor will ask questions about the patient's sexual history, including any recent sexual partners and the type of sexual activities that have taken place. This information can help the doctor determine if the patient is at risk for LGV and if further testing is needed.
In summary, diagnosis of LGV involves a combination of laboratory testing, physical examination, and patient medical history. The laboratory testing will look for the presence of the bacteria, while the physical examination will look for signs and symptoms associated with the infection. Finally, the medical history will give the doctor important information about the patient's risk factors and recent sexual activities.
