Individual tests

Epstein-Barr virus (EBV) is often symptomless, or the symptoms are indistinguishable from other mild illnesses. People with EBV infection usually get better in two to four weeks. After getting an EBV infection, the virus becomes inactive in your body but may sometimes reactivate. IgM antibodies indicate present infection, while positive IgG shows past exposure to EBV.

Estradiol, the most important form of estrogen, plays a vital role in sexual development. This test is used to determine the cause of early or late puberty, evaluate how the ovaries function, and monitor the progression of pregnancy or fertility treatment.
Testosterone is known as a "male" sex hormone, but females also have smaller amounts. It causes body hair, muscle growth, and a deepening voice after puberty in males. It controls sex drive, muscle mass, and helps make sperm. In females, testosterone is important for the growth of bones and muscles. A free testosterone levels test can help diagnose early or delayed puberty.
FSH works closely with another hormone called LH to control sexual functions. In women, these tests help find the cause of infertility, assess ovarian function, find the reason for irregular or stopped menstrual periods, and confirm the start of menopause or perimenopause. In men, these tests can find the cause of infertility, the reason for a low sperm count, or a problem with the testicles. In children, these tests can help diagnose early or delayed puberty.
HIV stands for human immunodeficiency virus. It weakens a person’s immune system by destroying important cells that fight disease and infection. There is currently no effective cure for HIV. However, with proper medical care, the condition can be controlled. When people with HIV do not get treatment, they typically progress through three stages. Stage 1, the most contagious phase, involves acute infection with flu-like symptoms. Stage 2 is a chronic infection with no symptoms, but HIV is still transmissible at this stage. Stage 3 is Acquired Immunodeficiency Syndrome (AIDS), the most severe stage of HIV infection, with an increasing number of opportunistic infections or other serious illnesses.
