A Woman's Guide to Pre-Conception Lab Tests

Hello, dear friends! The Wizey team is back with you.

Today, we have a topic that takes many people’s breath away—planning for a baby. You know, it’s like preparing for the most important journey of your life. Of course, you could leave spontaneously, but it’s much wiser to check the “technical condition” of your body in advance to ensure the path is smooth and the arrival at your destination is a happy one.

So, preparing for pregnancy is not a sprint, but rather a thoughtful preparation for a marathon. And it begins not with buying cute booties, but with a visit to the lab. Let’s, without panic or fuss, figure out what “check-up” a future mom should undergo to meet pregnancy fully prepared.

Step 1. The Foundation of Your Health: The Basic Check-up

Imagine you are building a house. You wouldn’t start putting up walls without making sure the foundation is solid, right? It’s the same here. Before moving on to specific “pregnancy” tests, you need to assess the general state of your body.

  • Complete Blood Count (CBC) with differential and ESR. This is your health passport. It will show your hemoglobin level (are you at risk for anemia, which will only worsen during pregnancy?), the number of red blood cells, white blood cells (is there any hidden inflammation?), and platelets (is your blood clotting okay?). It’s a simple but incredibly informative test.

  • Comprehensive Metabolic Panel (CMP). If the CBC is a passport, the CMP is a detailed questionnaire. We are primarily interested in:
    • Glucose: To check for any issues with carbohydrate metabolism and hidden risks of gestational diabetes.
    • ALT, AST, Bilirubin: Markers of your liver’s health. This organ works for two during pregnancy, and it’s important that it’s in excellent shape.
    • Creatinine, Urea: Indicators of kidney function, which will also face a serious workload.
    • Total Protein: The “building material” for you and your future baby.
  • Urinalysis. Another way to check kidney function and detect asymptomatic urinary tract infections, which can become a problem during pregnancy.

  • Blood type and Rh factor. This is sacred. You need to know both yours and the future father’s Rh factor. If the mother is Rh-negative and the father is Rh-positive, an Rh conflict can arise. This is not scary if you know about it in advance! Modern medicine handles this perfectly well; the main thing is to be aware.

Receiving a stack of forms with dozens of indicators can be overwhelming. What do all these “eosinophils” and “aspartate aminotransferases” mean? This is where our Wizey service comes in handy. It won’t give you a diagnosis over the internet (that’s a doctor’s job!), but it will help structure the information, highlight deviations from the norm, and help you understand what to pay attention to during your appointment with the gynecologist. It’s a great way to prepare for your visit and speak the same language as your doctor.

Step 2. Checking for “Uninvited Guests”: Infections

Pregnancy is a state of physiological immunodeficiency. The body intentionally reduces the activity of the immune system to avoid rejecting the fetus. But this makes it vulnerable to infections. Therefore, our task is to deal with them “on the shore.”

The TORCH Panel

This isn’t the name of a flashlight, but an acronym for the most dangerous infections for a fetus:

  • T — Toxoplasmosis
  • O — Others (often includes chlamydia, syphilis, hepatitis)
  • R — Rubella
  • C — Cytomegalovirus
  • H — Herpes simplex virus

It’s important to understand: a TORCH test is not just a “yes/no” answer. The lab determines the presence of antibodies—immunoglobulins M (IgM) and G (IgG).

  • IgG+ / IgM-: Excellent! You have immunity (you had the infection long ago), and it’s not a threat to you.
  • IgG- / IgM-: No immunity. This is a risk zone. For example, if you have no immunity to rubella, you need to get vaccinated immediately and then use contraception for 2-3 months. If you have no immunity to toxoplasmosis, you’ll have to forget about rare steaks, raw meat, and cleaning the cat’s litter box with bare hands during pregnancy.
  • IgM+ (with or without IgG): Acute phase of infection. This is a direct contraindication to conceiving right now. You need to get treatment first.

The Mandatory Minimum

  • Tests for HIV, syphilis, hepatitis B and C. No comments needed. This is a safety standard for you and your future child.
  • Vaginal swab for microflora and PCR tests for STIs. It’s important to ensure that the vaginal microflora is healthy and there are no hidden infections (chlamydia, mycoplasmosis, trichomoniasis, etc.) that could interfere with conception or cause harm during pregnancy.

Step 3. Tuning the “Control Center”: Hormones and Vitamins

Hormones are the conductors of our body. Ovulation, embryo implantation, and carrying the pregnancy to term all depend on their coordinated work.

The Thyroid Gland is Key

I can’t repeat this enough: TSH (thyroid-stimulating hormone) is the number one test for a woman planning a pregnancy. The thyroid gland is the main regulator of metabolism. Its hormones are critically important for the development of the fetal nervous system, especially in the first trimester. A mild, unnoticeable hypothyroidism (hormone deficiency) for you can be a serious problem for the baby. The ideal TSH level for those planning a pregnancy is under 2.5 mIU/L. If it’s higher, an endocrinologist can easily correct it with a small dose of hormones.

Vitamin and Mineral Reserves

These are not just “vitamins for beauty,” but strategic resources.

  • Folic acid (Vitamin B9). This is the alpha and omega of planning. You need to start taking it 3 months before the intended conception. It has been proven that an adequate level of folate reduces the risk of neural tube defects in the fetus by 70%. This is a case where a small pill works a big miracle.
  • Vitamin D. This is not just a vitamin, but a prohormone involved in a thousand processes—from immunity to calcium absorption. Almost all of us in northern latitudes are deficient in it. Be sure to check your level (25(OH)D test) and, if necessary, start taking it under a doctor’s supervision.
  • Ferritin. Note, not hemoglobin, but ferritin! Hemoglobin is the iron that is already “at work,” while ferritin is the iron reserves in “storage.” During pregnancy, iron consumption is colossal. If you enter it with empty “stores” (low ferritin), anemia is almost guaranteed. And that means hypoxia for both you and the baby.

Sometimes, the results of different tests may seem to contradict each other or paint a complex picture. For example, a slightly elevated TSH, borderline ferritin, and some other strange numbers in the metabolic panel. Seeing these interconnections can be difficult, especially when you have results from different labs at different times. Our AI assistant, Wizey, is trained to look for such complex patterns so you can go to the doctor with a structured inquiry.

A Final Word, or “What to Do with All This?”

This list may seem dauntingly long. But please, don’t see it as an exam you have to pass with flying colors. See it as an act of love and care for yourself and your future child.

The main rule: do not self-diagnose or self-medicate!

This checklist is not an instruction manual, but a map of the terrain that you bring to your navigator—your gynecologist. Only they, seeing the full picture—your tests, medical history, lifestyle—can create an individual preparation plan for you.

Family planning is a conscious and very beautiful step. And the better you prepare your “ship” for departure, the smoother and more joyful your nine-month journey will be.

And yes, it is also highly advisable for men to undergo a medical check-up before conceiving a child. We will talk more about this next time.

With care for your future, The Wizey team.
