Unfortunately, we all get sick sometimes and, no matter how much we want to, we have to visit doctors, get tested, and so on. But it is very difficult to understand the tests if you do not have a medical education, especially when it comes to blood tests. I will not be walking around anymore, and I present to your attention an application for iPhone “Blood tests”. The application will help you not only figure out what kind of strange abbreviation appeared in your outpatient card, but also tell you which category the analysis belongs to, what standard indicators should be and what deviations can be caused by (pregnancy, weakened immunity, and so on). By the way, in spite of the fact that the application is called “Blood test”, information is available to you about some other types of tests and even clinical studies. The application has a simple interface with 4 main tabs on the bottom line of the screen. It is also worth noting that in spite of, let's say, not quite an ordinary “genre”, the application is quite colorful and cute. The “Analyzes” tab lists all possible analyzes that probably only exist. These are general, biochemical, immunological, hormonal blood tests, and so on. There are more than 150 indicators in total, and the developers plan to update and supplement the list. By clicking on any analysis you are interested in, you will find out its “composition”, so to speak. If you are interested in any specific indicator, then just click on it and you will find out what this indicator is, what it is responsible for, what are its standard values, and for what reasons it can be increased or decreased. The application is also equipped with a convenient search, in case you need to find information about the analysis, but you do not know in which category to look for it. There is such a useful application in App Store. Do not be ill!
