How to use it?

The testing procedure always starts with proper preparation.

Place the contents of the box on a clean, dry, flat surface (e.g. table). Then comes the testing:


Prepare the test device and pipette. Remove them from the protective envelope (tear the tape) and put them to hand (you'll need them later). Remove the desiccant bag.


Prepare the chain. Hold the chain without touching the release button. Open the chain cover with a 1/4 turn until you feel it detach from the chain, then continue twisting (2-3 turns). Don't pull, just twist and discard the lid when you're done. (fig. 1&2)


Clean the end of the middle or ring finger with cotton wool soaked in alcohol. Massage the disinfected finger towards the tip for 10-15 seconds to stimulate blood circulation.


Press the end of the chain firmly against the side of the previously disinfected finger, then press the release button (fig. 3)


The tip will automatically retract into the body of the device.


Massage the fingertip to get a sufficient sample of blood. (fig. 4)


Without depressing the pipette balloon, touch the plastic pipette to the blood sample (Fig. 5). Blood migrates into the pipette by capillary action towards the line marked on the pipette. You can massage your finger again to get more blood, if it doesn't touch the line on the pipette. If possible, avoid air bubbles.


Place the blood collected with the pipette into the sample port of the device by pressing the pipette balloon (Fig. 6).


Wait 30-40 seconds for the blood to be completely absorbed into the sample port. Unscrew the blue cap of the dilution solution dropper bottle (leave the white cap tightly screwed on) and add the dilution solution as follows: hold the dilution solution dropper bottle upright and slowly add exactly 4 drops into the sample port of the device (fig. 7) with an interval of 2-3 seconds between drops.


Read the result in the first 5 to 10 minutes. The result is not to be interpreted after 10 minutes.

The colour and intensity of the lines are not important for the interpretation of the test result.

Questions and answers

1. How does the Blood Pregnancy Test work?
When a woman becomes pregnant, her body begins to produce a hormone, human chorionic gonadotropin (hCG), which is released in the blood, where its concentration increases over time. Pregnancy test from blood detects the hormone hCG in the blood. Pregnancy test from blood uses a specific pair of antibodies that detect hCG hormone in the blood, when the hormone level is at the at least 25 IU/L (determined against WHO reference*) or higher. * World Health Organization
2. When should the test be performed?
You can use the pregnancy test Blood pregnancy test in any time of day or night. Blood pregnancy test can detect pregnancy earlier than a classic urine test, because the hCG hormone produced in the placenta is first released into the bloodstream and then into the urine. Therefore, you no longer need to collect urine first thing in the morning to increase the likelihood early detection of pregnancy.
3. Can the results be incorrect?
The results are correct, as long as they are carefully observed instructions. However, the result may be incorrect if The blood pregnancy test is moistened before testing, or in if the amount of blood in the sample is not correct. Pipette plastic box supplied in the box helps ensure that the volume of blood collected is correct. Certain medicines containing hCG or used in combination with hCG (such as Pregnyl, Porfasi, Pergonal) and conditions Rare medical conditions can lead to a false positive result. Alcohol, painkillers, antibiotics, birth control pills, treatments Hormonal drugs containing clomiphene citrate (such as Clomid, Serophen) or analgesics should not affect the outcome test. The test may show a false positive result if you have had an abortion spontaneous, had an abortion or gave birth in the last 8 weeks. This is because hCG is still present in the body yours.
4. How is the test interpreted if the colour and intensity of the T and C lines differ?
The colour and intensity of the lines are not important for interpreting result. The lines should only be homogeneous and integral. The test must be considered positive regardless of the intensity of the colour test line (T), even if it is weak.
5. What is the meaning of the line under the C (control) mark?
When this line appears, it means that the test was performed correctly.
