Home pregnancy tests can be very accurate if used properly.Since the earliest recorded history, women have had a strong desire to know whether they are pregnant as early as possible. The body goes through countless changes in the first trimester, and one of the first indicators is a change in the hormones that leave the body through urine.Ancient Egyptians relied on a form of urine testing to determine pregnancy status way back in 1350 BCE. A woman urinated daily on wheat or barley seeds and if the plants grew, it meant she was pregnant. Modern-day validation suggests that test was about 70% accurate in detecting human chorionic gonadotropin (hCG), a hormone produced by a woman’s body soon after implantation of a fertilized egg inside the uterus.

Responsible for more than 9 million cases and 110,000 deaths worldwide, typhoid fever remains a major threat to public health across the developing regions of the world. According to the World Health Organization (WHO), typhoid fever is endemic in many parts of Asia, Africa, and Latin America. It disproportionately affects children and young adults in communities with inadequate sanitation and limited access to clean water.

Syphilis is a Sexually Transmitted Infection (STI) that is usually passed on during oral sex, anal sex, skin-to-skin contact or when sharing sex toys. Once seen as a relatively rare infection in Australia, in 2020, syphilis infections increased by nearly 90% from recorded rates in 2015.

The window period for syphilis is 3 months. This is the time between coming into contact with syphilis and when a test is able to detect it. If a sexual partner has let you know that you may have come into contact with syphilis, or if you have symptoms that sound similar to syphilis, don’t freak out. But it is a good idea to see a doctor, as they might decide to give you medicine straight away. A great list of doctors to go to can be found here, or you can visit your local sexual health clinic.

Over the past decades, paper-based lateral flow immunoassays (LFIAs) have been extensively developed for rapid, facile, and low-cost detection of a wide array of target analytes in a point-of-care manner. Conventional home pregnancy tests are the most significant example of LFAs, which detect elevated concentrations of human chorionic gonadotrophin (hCG) in body fluids to identify early pregnancy.

The first home pregnancy test was introduced in 1976. Since then, pregnancy tests have become the most common diagnostic assay used at home. Pregnancy tests use antibodies to detect human chorionic gonadotropin (hCG).

A pregnancy test is used to determine whether a female is pregnant or not. The two primary methods are testing for the female pregnancy hormone (human chorionic gonadotropin (hCG)) in blood or urine using a pregnancy test kit, and scanning with ultrasonography.[1] Testing blood for hCG results in the earliest detection of pregnancy.[2] Almost all pregnant women will have a positive urine pregnancy test one week after the first day of a missed menstrual period.[3]

Home pregnancy tests are sold almost everywhere. You can find them in most stores, from your major retailers to your grocery store, convenience store, and even discount stores.

Pregnancy tests work by detecting levels of human chorionic gonadotropin (hCG), a markers of pregnancy in a person’s urine or blood. Home tests can usually detect pregnancy 12–15 days after ovulation.

Pregnancy tests can sometimes give a false negative result to women several weeks into their pregnancies, according to research by Ann Gronowski, PhD, a professor of pathology and immunology at Washington University School of Medicine in St. Louis. Her findings led the FDA to change its standards for evaluating new pregnancy tests, but old tests with the false-negative problem are still on the market.

If you’ve recently had sex and your period hasn’t started yet, or you are experiencing pregnancy-like symptoms such as nausea or fatigue, you may be worried that you are facing an unplanned pregnancy.
