How to Interpret Pregnancy Test Results and Beta HCG

Most of the questions regarding pregnancy tests are related to the result. Interpreting them is not always so easy; however, with this little help it can become much simpler to understand what the report means. When we do the blood or urine test at home, we may be unsure of those numbers or the test line , because not everyone knows how to interpret what the result of the pregnancy test means.

It has two lines, but one is too weak? What does this number of numbers mean in the result of my HCG beta? Come on then for the explanations!

Pharmaceutical Tests

I’ll start with the pharmacy test. These tests are increasingly effective in detecting the HCG hormone. Some of them promise effectiveness in up to 99% of cases when there is a menstrual delay. We can say that the test with two lines is positive yes , be it of any color; however, some of them bring more doubts than certainties.

The pregnancy test is able to react to the amount of HCG in the urine. It should be done by dipping the absorbent tip into the pee and then waiting for the recommended time on the label for each brand. Usually, the result comes out in three to five minutes. Two lines is positive, regardless of the color of the second line (the test line).

The reason this line is clearer is the amount of HCG present in the urine and also the sensitivity of this test. Some tests are able to detect 25mUi of HCG in a woman’s urine. Others, starting at 10mUI. This difference seems to be small, but for an initial pregnancy it is a considerable advance. The Famivita pregnancy test , for example, is a 10mUI high-sensitivity test that can detect pregnancy up to two days before menstrual delay. You can find your pregnancy test here in our online store.

When the line is much clearer than the control line, it can indicate that the quantity is still low and that the production of HCG is very recent. It is advisable to repeat the test in 48 hours, which is a considerable time for the hormone to rise and become more evident to the test reagents.

The result of the pharmacy pregnancy test should be interpreted as positive if there are two lines, and negative if there is only one line, which is the control line. If there is only one test line or none of these, the test is invalid .

Test Result Blur

Another situation of those who use the pharmacy tests is the blur of the test. For those who have never taken a pharmacy pregnancy test, imagine a foggy window. This smudge of the ink dye used to demarcate the result can be confusing if it is completely spread over the test area. Therefore, even if a subtle line appears there, it is necessary to disregard it and do it again with a new strip.

Evaporation Line

I couldn’t talk about a pregnancy test without talking about the evaporation lines. It can come up on the pharmacy test and shuffle everything. What was once a negative can become a positive, and misinterpreting the pregnancy test result can have serious consequences.

The ideal is to read the result in a maximum of 10 minutes ! After this period, a false positive is risky through the evaporation line or in tests with blue dye, such as Clear Blue, for example.

How to Interpret the Result of the Beta HCG Pregnancy Test?

Beta is an even bigger question for many women. The problem occurs exactly in the result of the blood pregnancy test, or better, of the quantitative beta HCG , the one that shows exactly the amount of hormones that are in the woman’s blood. Some laboratories just put the number and the minimum reference to the side; however, due to lack of experience, insecurity or not believing in what they are seeing, the result of the beta pregnancy test is one of the champion questions here on the site.

We can say that, to be sure of what is written in the report, we must take into account the laboratory reference , so the pregnancy result can be easier to read. Let’s say that the laboratory has a minimum amount of 25mUI of HCG in the blood to consider positive and the test gives 1.2 mUI. Therefore, this woman is not pregnant. The reference for most laboratories is 25 or 50 mUI. The following are some results to be used as examples. Follow the reasoning:

Sample Results

Result: 124.00mUi> Positive because it would be above the reference value, ie 25 to 50 mUI.

Result: 2.4mUI> Negative , any sample below 25, in this case, is negative for pregnancy.

Result: > 25mUI> Positive , since the sign in front of the number says that the sample has an amount greater than 25mUI.

Result: <25mUI> Negative , as it shows that the amount of hormones is below 25mUI.

Result: 10mUI> Undetermined , the test contains HCG samples; however, it is still not enough to show the positive.

Any pregnancy test result above 25 or 50 is certainly positive; however, it is advisable to repeat in one week to see the evolution of the test (when it is quantitative beta). Ideally, the test will almost double its value in up to 3 or 4 days. To accompany this evolution, it is recommended to do this within this period of time.

Indeterminate Result

Indeterminate tests are common to happen. They occur because the pregnancy is recent. The tendency for indeterminate tests is to evolve. However, if they continue in the same situation in 10 days, it is likely to be a chemical pregnancy or even a micro abortion.

The important thing is to repeat the blood test in the same laboratory. If this is not possible, the parameter will change and it is not recommended to take the old exam into consideration. Thus, it is advisable to repeat in the same place to avoid misunderstandings or scares.

The beta evolves faster for some women than for others, but in all of them it should show satisfactory results in one week . Be careful and don’t despair, repeat and talk to your doctor and, of course, no rash ultrasound. Wait for the medical indication to do, ok?

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.
