How Does a Pregnancy Test Work?

Pregnancy tests detect something called Human Chorionic Gonadotropin (hCG). Simple right? I mean who doesn’t know what Human Chorionic Gonadotropin is? Well I didn’t, and maybe you don’t either, so let’s find out.

Human – Not a dog, an Oak Tree, a Transformer, or any other space creature. The following diagram should help.

Human and not human

Chorionic – This one’s unfamiliar for sure. The root word here is “chorion” which refers to the outer membrane surrounding a developing embryo. Embryo describes a stage of human development, just like infant, toddler, or adolescent, and refers to a human in their first eight weeks of development. After eight weeks the growing baby is called a fetus, and we’re called infants or newborns on our birthday. So chorionic refers to something that comes from the chorion.


This is not Gonadotropin.

Gonadotropin – This is a specific type of hormone. Think about it like this, Bulldog is to dog what Gonadotropin is to hormone.

Putting it all together, Human Chorionic Gonadotropin (hCG) simply means a hormone produced as a human embryo (baby) develops.

Pregnancy tests work on a chemical level, using a kind of molecular magnetism. The test contains a molecule with some color in it that is designed to attach itself to hCG, and when it finds the hCG the color is released and it shows up in the tiny window on the pregnancy test.


hCG increases as the baby grows, so the reliabilty of the test is better two weeks after conception than it would be just one week after. This is why a test that shows “not pregnant” may actually be inconclusive because the hCG levels may be too low to show up on your test. If you’re in doubt you should schedule an appointment with your doctor.

What is (are): Support Groups?

Sometimes you just need someone to talk to. Life’s crazy enough as it is, but the possibility of having a baby on the way or managing all the wonders of parenting can make it crazier still. Our classes will empower you to make educated decisions and be as prepared as possible for whatever is happening in your life, but sometimes, like I said before, you just need someone to talk to.

Support (1)

Every once in a while, when you come in for class, we’ll forgo the DVD and hold  a support group instead. Instead of a lesson, one of our trained team members will set up a conversation for your class that day. Maybe you’ll talk about parenting struggles you’ve been having, maybe a discussion about the soreness and fatigue associated with pregnancy, or maybe it will be a chance to share some of the good things happening in your life. It changes. The goal is to give you a chance to be heard, and to hear from others going through some of the same things.

Relationships are what we do. That being the case, never hesitate to pull one of our team aside to talk, if that’s what you need. We all know there are days when life is so hectic it would be too hard to focus in class, and maybe the issue to intimate to talk about in a room full of people, if that’s ever the case for you, just let us know. Assuming we have enough people to cover everything, we’ll sit down for a little one on one time and hear your heart. We’re here to serve you, so don’t be shy.

Am I Pregnant?

Each and every day thousands of women and teen girls receive positive pregnancy results. For many, the thought or feeling of being pregnant never even crosses their minds. Although every female body is different, there are however a number of signs you may encounter before knowing your pregnant.
These signs are:
• Bleeding/ Spotting
• Swollen/ Tender Breast
• Fatigue/ Tiredness
• Nausea/ Morning Sickness
• Backaches
• Headaches
• Frequent Urination

If you are experiencing any of these signs you may or may not be pregnant. The only way of knowing you are in fact pregnant is by taking a pregnancy; in which here at the PHI Center is both free and confidential. If you are seeking help come on in and we would be happy to assist you.

Announcing the retirement of a faithful servant!

Here at the PHI Center we are always on the move; things are constantly changing, people are growing, and our ministry is evolving daily. However, after seventeen years of service, we would like to announce the retirement of our very own Barbara who will be leaving at the end of this month. It will be very difficult to fill her position as she has been such a rock for us all these years. Her presence daily will be missed but not forgotten. We wish her the best in this new journey in life called RETIREMENT.

We’d Love To Talk With You
