The modern woman has the opportunity to choose which test to use for home pregnancy determination. The choice is great - these are simple strips, more complex cassette tests, and even reusable electronic devices. Most of the fair sex are sure that the test must necessarily correspond to the combination of price and quality, and one of the most popular in this ratio is the Evitest brand tests.
What are they?
Evitest is a German brand, which once again confirms that German quality is not just a popular phrase, but also a certain guarantor of reliability, no matter what it is about. The manufacturing company is known as one of the world's leading manufacturers of test diagnostic systems. She produces ovulation tests, pregnancy tests. Diagnostic systems for the "interesting position" in the home of this brand are represented by four names.
Evitest one
The simplest of all the options available. It is a regular express test, strip strip. There is one single-use strip in the box. It sinks into urine for a set time.
Evitest plus
This is also a simple system, but it consists of two strip strips. One can get an answer to a question of interest, and the second is designed to confirm or refute the primary result. It is obtained by dipping the distal part of the strips into urine.
Evitest Proof
The tablet version, which, according to the manufacturers, has a higher accuracy, which is provided by the design itself - the test strip is reliably covered with a plastic case. The kit includes a pipette that collects collected urine. The liquid is applied in one window in the body, and in the other after 5 minutes the result appears.
Evitest perfect
These are jet systems. This means that there is no need to collect urine in a container, it is enough to bring the device under the urine stream while urinating. The model has a perfectly acceptable holder that facilitates the procedure and an absorbent tip.
This is the most expensive test in the Evitest line, but it is called the most accurate and hygienic.
How do they work?
While there is some variation in the use of the Evitest species described above, the main “mechanism” of action is completely identical. Each system determines pregnancy by the presence of chorionic gonadotropin molecules in urine - the hCG hormone. A chemical reagent is applied to the test area of the strips, into the absorbent tip of the jet test, which, when a substance is detected in the urine, enters into a chemical reaction with it, which ensures the coloring of the second strip.
HCG is produced in the female body in large quantities after the embryo is implanted, and the embryo is fixed in the cavity of the reproductive organ, where it will have to spend the next 9 months. Implantation usually occurs one week after conception, the average time is from 6 to 9 days... After implantation, the level of the hormonal active substance doubles every two days.
The hormone penetrates into the urine a little later than into the blood plasma, but usually by the beginning of the delay of the next menstruation, its content in urine exceeds the sensitivity threshold of the test system, and hCG molecules become distinguishable for the reagent of most existing test systems. That is why it is recommended to test no earlier than the first day of missed period. And the earliest deadline is 4 days before the delay... But it is mostly only ultrasensitive tests that can determine pregnancy before the delay begins.
Evitest's sensitivity does not allow these tests to be classified as such. It is 20 mIU / ml, which indicates high, but not ultra-high sensitivity. This threshold for the perception of the active substance in the urine suggests that tests can determine pregnancy not only after a delay, but also a couple of days before it begins.
Pros and cons
All tests of this brand are disposable - strips, cassettes, and inkjet systems. There is no other sensitivity level other than the one indicated above. At the same time, each of the tests of this brand has its own advantages and disadvantages.
Evitest one
Has only one strip. And this is an undoubted disadvantage, since for confirmation you will have to go to the pharmacy again to buy a second test. The disadvantages of the system also include the need to collect urine in a special container before self-diagnosis. This can be inconvenient when the woman is outside her home toilet and is time consuming to diagnose. The advantages of the system are its low price and availability - tests of the One type are available in any pharmacy.
Evitest plus
Contains 2 strips. The double test is more practical as it saves a woman from having to buy a second strip separately. The strips in the package are presented in two separate packages. The undoubted plus of this system lies in its price.
If you buy 2 separate strips, they cost significantly more than 1 double set.
The disadvantages of the test are the same as for a single strip - you need to collect urine.
Evitest Proof
There is no need to look for a urine container as it is included. There is also a pipette in the box, which should be used to collect and bury urine in a specially designated space in the body. Among the advantages, women call in their reviews a rather high accuracy, hygiene of the test.
But the obvious disadvantage is the price - the test of the tablet type is much more expensive than a strip-strip.
Evitest perfect
The inkjet test is convenient to use, the holder helps you to carry out the test in just a few minutes with maximum comfort and hygiene. The plus is that the woman is not "tied" to her own toilet, she can take the test anywhere - at work, in the university toilet, etc. Collecting urine before testing is not required. The system is considered highly accurate.
The only problem - the highest price among the entire line of diagnostic systems.
How to use?
Each model of the Evitest test is accompanied by detailed instructions that will help to diagnose correctly and obtain a reliable result. Please note that compliance with the manufacturer's requirements is a very important condition if you want to get an accurate answer to your question.
Evitest One and Evitest Plus
Care should be taken in advance to ensure that there is a container in which you collect urine. This can be a special plastic container from a pharmacy or just a glass jar, for example, from baby food. It must be clean and dry. After collecting the urine, you should remove the strip from the bag, holding it by the part opposite the distal end. On the side that is considered the immersion zone, the strip should be dipped into the urine to the level indicated by the dark strip. You need to keep it in urine for about 5 seconds., after which the strip is taken out and laid out on a flat and dry horizontal surface.
After 3-5 minutes, you can evaluate the result. But do not delay, as after 10 minutes the verdict will be invalid, the test may show abnormalities that are not related to pregnancy, such as a gray strip where the second strip was. Such a strip is a trace of the reagent after drying, it does not indicate pregnancy. A positive result from Evitest looks like raspberry or purple 2 stripes. Negative is represented by one bar in the control area.
Evitest Proof
Collect the urine in a container included in the kit. With a pipette, which is also available, you need to collect a little urine. Place the cassette on a flat surface; do not try to hold it in your hands. 4 drops of liquid are applied to the window. Then you need to wait from 3 to 5 minutes, but no more than 10 minutes, to get an answer to the question about the presence or absence of pregnancy.
Evitest perfect
Remove the cap from the tip and place it under the stream of urine while urinating for 5 seconds. Then the cap must be returned to its original place and the device must be placed on a flat surface away from water for 3-5 minutes. Then you should evaluate the result.
Which to choose?
Which of the presented tests is better to choose for use is up to you. It depends on your financial capabilities and personal preferences. If we talk about accuracy, then all four types are characterized by high accuracy, which is confirmed by the reviews of women on thematic forums on the Internet.
If you are sure that the test will need to be done once, you can do with One. If you have to do the test again, it is better to buy a double version, so you can save a lot.
The main thing is to choose a quality product. Take the system only at the pharmacy, avoid shopping at the supermarket, as storage conditions are often not met there... Be sure to evaluate the expiration date as an expired reagent cannot guarantee a normal chemical reaction.
If you do the test before the delay or immediately after it starts, do the test on morning urine - it is more concentrated and dense. If you have taken hCG drugs, then there is no reason at all in conducting a home test. If you get a questionable result, retest after 48 hours.
