Human Karyonic Ganadatrophin, the famous HCG. Pregnancy hormone !!! When fertilization takes place, the zygote goes slowly to the uterus and if the endometrium (the famous layer that flakes off during menstruation ) is in good condition for thickness and texture, it fixes giving rise to pregnancy really now.
HCG is one of the important responsible for pregnancy, it prevents the corpus luteum from being destroyed, the corpus luteum is the one that excretes the progesterone and there it was where the egg was matured and then it was excreted and taken to the tubes where it was fertilized by the sperm. This is a hormone unique to pregnancy and rises very quickly at the beginning, since it is at this stage that it is paramount. Through it you can detect pregnancy and also the approximate time of pregnancy.
The pharmacy tests have a reagent that causes of this positive line to appear when there is HCG in the urine of women and have laboratory tests have the same function and are very similar in the run method. The biomedical doctor only changes urine to blood plasma and if it is positive, he can measure the amount of HCG present in the plasma sample.
If the test result is written only REAGENT, the test was done just like the urine test, without hormonal counting, it is the qualitative HCG test . But if it comes like the one in the photo below with a hormonal count it is a quantitative exam (which measures the hormonal count).
When do I consider the HCG Hormone Test to be positive?
This is an example of a quantitative HCG laboratory test result of 307.2 mui / ml, and above 25 mui / ml is already positive . So I was really pregnant! She is approximately 3 weeks pregnant according to a table that exists to compare the amount of HCG present.
My pregnancy test done in the last pregnancy
The tables are there to help, but end up getting in the way sometimes, as it may happen that the woman ovulated after the period that menstruation might indicate, such as: the normal cycle is approximately 28 days, and there are 14 days to go. from the first day of menstruation, then
28 – 14 = 14
Menstruation would occur around the 14th day of the cycle, but as in my case my cycle was 31, 33 days, I considered that menstruation could be around the 15th day until the 17th day causing a difference that is great at this stage .

There are several tables, but it was the one that worked best for me in two pregnancies. There are also possibilities of appearing outside of pregnancy , but there it is very rare, there are some types of tumors that can excrete HCG, but in a small amount that a pregnancy test would not reveal.
My exam was undetermined several times until I was positive, would I be a little pregnant? No, this is not even rare, the problem that some laboratories have a rather high limit for positive, and so it is in the middle, neither discards nor confirms the pregnancy.
It is advisable to repeat the test in 48 hours, because within this period it is expected that it will practically double its value. However, in some cases the test may not double or increase, on the contrary, then you should consult your doctor because it may have had a fertilization and a beginning of implantation and there may be a chemical pregnancy .

My name is Dr. Alexis Hart I am 38 years old, I am the mother of 3 beautiful children! Different ages, different phases 16 years, 12 years and 7 years. In love with motherhood since always, I found it difficult to make my dreams come true, and also some more after I was already a mother.
Since I imagined myself as a mother, in my thoughts everything seemed to be much easier and simpler than it really was, I expected to get pregnant as soon as I wished, but it wasn’t that simple. The first pregnancy was smooth, but my daughter’s birth was very troubled. Joana was born in 2002 with a weight of 2930kg and 45cm, from a very peaceful cesarean delivery but she had already been born with congenital pneumonia due to a broken bag not treated with antibiotics even before delivery.
