Early Pregnancy Testing – What You Should Know

Early Pregnancy Testing

Early pregnancy testing is important because it allows the prospective mother to make the necessary preparations for her baby and herself. After all, pregnancy is not an easy thing to go through especially if the woman does not have a husband or a partner to help her with the readying and the adjustments required to ensure that a safe delivery is accomplished.

 

Early Pregnancy Testing – The Tests

 

Nowadays, with the many advancements made in health sciences, it has become possible to find out if a woman is pregnant for sure in as early as 48 hours after fertilization. This particular test is called the Rosette Inhibition Assay for Early Pregnancy Factor (EPF). According to studies, EPF can be detected in the blood stream within the first two days of fertilization, making this process the quickest method of determining and confirming pregnancy. It is important to note though that this laboratory test is expensive and time consuming thus it is rarely done at will or by request in many hospitals.

 

A Rosette Inhibition Assay for Early Pregnancy Factor or EPF is an effective method for early pregnancy testing. Its accuracy as a pregnancy test is high according to several studies and researches done by numerous reputable laboratories all over the world. This testing was first done in 1979 both to determine pregnancy and to monitor the viability of ongoing pregnancies in human and mice. Interest in this kind of test has continued over the years although the most commonly used in many households today test for the presence of HCG or Human chorionic gonadotropin which can only be detected six to twelve days after the ovum or egg is fertilized by the sperm.

 

The common pregnancy test kits that can be bought in any drugstore today are test for the presence of HCG or Human chorionic gonadotropin in the blood or urine of the woman. Most of these kits are based on lateral flow technology which, simply put, are devices that detect the presence of a target analyte in a given quantity of sample. In the case of an early pregnancy testing kit, the analyte is the HCG and the sample is the woman’s urine which is preferably obtained in the morning where the level of Hcg is at its highest.

 

Early Pregnancy Testing – Conclusions

 

When doing a pregnancy test, it is important to keep in mind that a false positive reading may be obtained if it is done too early. Menstruation is expected to occur after 14 days of ovulation therefore the chances of a false negative once the period has been delayed is significantly lowered. The accuracy of a test for pregnancy therefore is more related to the day of ovulation than the day when intercourse or insemination happened. A sperm, once inside the fallopian tube of a woman can survive up to five days after it is deposited there. Furthermore, it can take up to 12 days total for implantation to occur which give false negative results until seventeen days after sex could have occurred. All in all, testing earlier than three weeks after the act was done can still give a falsely negative result from an early pregnancy testing kit.
