There can be quite a few subtle differences between each kit that is available on the market. The first difference is of course price. There is a considerable price difference among the different test kits. The prices typically start around $100 for a single test. The price differences are usually due to a number of diseases tested for. In a few cases, the increased price is due to improved accuracy.
Accuracy can vary for each disease tested for. Certain kits offer better accuracy for certain diseases. Accuracy also seems to be a variable in each kit regardless of price. Certainly, the more expensive testing has better accuracy results across the board for all diseases. It is important to note the different accuracy percentages for each disease no matter the price of the kit.
Some kits will allow you to choose which disease is tested. Typically at home STD kits offer a range of diseases that will be tested. There are even at home test kits for all common STDs. The most convenient of kits will separate out each disease separately, these are also the most economical of diagnostic kits. However, if you want to test for several different diseases getting a kit that covers the most diseases is more economical than ordering a separate test for each disease.
The instructions presented by each company vary greatly. The reason for this is mostly due to the fact that each company uses a different laboratory. The sample collection and mailing methods vary depending on the specifications of the laboratory used. Certain companies will have very detailed directions and some have received criticism on the detail of the directions provided. The type of fluid that is being collected also has a big difference over the method of collection and shipment.
Other differences involve the laboratory that is used. Most kits will have a laboratory that is automatically used as a default. There are some companies that allow the consumer to choose the laboratory that is used. There are yet other companies that work in conjunction with any laboratory in the consumer’s local vicinity. With this type of diagnostic kit, the sample is collected at an actual laboratory. The test results are sent directly to the home.
