Further advances in home tests came only in recent years. I remember was that it was the seventies, when my uncle, a diagnosis of diabetes, which allowed the American diabetes test strips paper association needed to urinate on them and return. When the results came back positive for sugar in urine, which underwent a blood test at the doctor's office requires a fasting sample and then sample a meal body for several hours. It was a case all day. Now it has a meter and we all have to do is bite his fingers and get results in about 5 seconds. They work in one, to monitor levels of blood sugar over a 24 hour basis. All you have to do is press a button.
One of the tests was at home earlier in pregnancy testing. A document of ancient Egypt lists of early pregnancy tests dating back to 1350BC. The woman, who suspected she was pregnant urination for seed wheat and barley in several days. When wheat has increased, it meant a girl, and if the barley grew, it was a male, although there were a seed then the woman was not pregnant. If the theory has been tested in the 1960s showed that the wheat / barley trial was correct, about 70% of the time. The test for the hormone that increases when women are pregnant, were in the 1930s.
Urine was injected into a rabbit. The FDA has tested the first pregnancy in 1976. He went on the market in 1978. The test costs $ 10 and lasted about 2 hours. The set consists of sheep red blood cells, a small bottle of pure water, a drug pipette and clear support for a plastic test tube.
