Two Types of Pregnancy Blood Tests
Pregnancy blood tests can reveal all sorts of information for doctors and their pregnant patients, including clues
to potential birth defects and diseases. In this article we will look at the initial test – that of determining
pregnancy by blood test.
There are lots of vague and misunderstood issues that come into play with pregnancy – especially with teens and
first-time mothers. A healthy awareness of the whole process leads to understanding and a better chance of applied
knowledge yielding good results which means a healthy and happy childbirth.
Pregnancy Testing
In today’s marketing and sales driven world, it is the rare consumer who has not seen TV commercials for
do-it-yourself home pregnancy tests. Simply put, these urine based tests offer a color coded yea or nay answer to
the pregnancy question. The issues of privacy and early detection have their own parameters; these are both social
and medical issues.
A blood serum test is the preferred pregnancy blood test regularly performed by doctors and clinics. The results
are similar but there are differing tests available using blood rather than urine as the test medium.
The thing being tested is called human chorionic gonadotpopin (HCG) and there are two different pregnancy blood
tests with different goals.
Qualitative and Quantitative
The qualitative pregnancy blood test is a test designed to determine whether HCG is present in the bloodstream, and
in a sense is similar to at-home tests – it gives a yes or no answer. This is a one-time pregnancy blood test and
serves the purpose of confirmation of pregnancy.
With the quantitative method it is not a question of preference, but rather the need for more data. The
quantitative method is definitely more involved – not just a yea or nay but an actual measurement of HCG. The
qualitative followed by quantitative pregnancy blood tests combine to give physicians a powerful monitoring tool.
Physicians use HCG levels in the bloodstream to gauge healthy and normal pregnancy.
When and How?
HCG levels are rather predictable at different times of pregnancy, starting with conception. Within regular
intervals, the levels change in the body and measurements can help point to existing conditions that are linked to
birthing difficulty. For this reason, the family physician, OB/GYN doctor or specialist may call for these
quantitative pregnancy blood tests to be taken a number of times or in a weekly series, especially during a
problematic pregnancy.
Enough Already!
Of course, pregnancy usually becomes visible at some point. Further testing is not just about the urine or blood
during pregnancy, but rather potential problems are the concern. For a healthy and safe pregnancy, start early with
a visit to a physician or clinic. Let learning be part of the process and try to enjoy every moment.
