David one step sperm test strip cassette in vitro diagnostic test kit with wholesale price
How does the DAVID Male Fertility Test work?
The test is a rapid qualitative test detecting the presence of sperm in human semen at 15,000,000 sperm/mL or above. A positive result on this test strip indicates a sperm concentration greater than or equal to 15 million sperm/mL, the current World Health Organization (WHO) reference value of a fertile sperm count, for a normal semen analysis.
What does a positive result mean?
Positive test result can not prove fertility but only means that sperm concentration in the semen sample is not less than 15 million / ml because there are a variety of factors that cause infertility in addition to sperm concentration. If a couple can not conceive after a year or longer time of normal and unprotected intercourse, it is recommended to consult a specialist.
If the result is negative, what should I do?
A negative result indicates that your sperm count is less than 15 million per milliliter, which is below that of most fertile men. However, the result of this test alone does not prove infertility, as there are other factors affecting fertility. However, some men with sperm counts below this level are still able to father children naturally. It is also important to understand that your sperm count can vary from day to day. If there is any suspicion of test result, it is recommended to collect sample again after an interval of more than seven days but less than three weeks for test again. If the result is still negative, it is recommended to consult a specialist.
