> Preeclampsia risk evaluation is a routine part of your prenatal care, combining blood pressure and urine checks with early assessments to identify potential risks.

Preeclampsia screening is a continuous process integrated into your prenatal care, designed to identify potential risks for a condition that can affect both parent and baby. This proactive approach helps you and your care team make informed decisions about your pregnancy journey.

## What it is
Preeclampsia is a pregnancy-specific condition characterized by high blood pressure and often, signs of damage to other organ systems, most commonly the liver and kidneys. It's a condition that requires careful monitoring. Screening for preeclampsia is a universal recommendation and is integrated into your routine prenatal care from your very first visits, just like your [First Prenatal Blood Panel](/tests/first-prenatal-blood-panel) helps establish baseline health markers. This screening involves regular blood pressure (BP) monitoring and urine dip tests for protein at every prenatal appointment.

Beyond these routine checks, a first-trimester risk assessment can also be performed. This assessment considers your medical history, including any prior preeclampsia, chronic hypertension, autoimmune diseases, your age, and BMI. In some centers, specific first-trimester biomarkers are also used to refine this risk assessment. Understanding your individual risk profile early on allows for a more personalized care plan.

## When and how it happens
The primary components of preeclampsia screening — blood pressure checks and urine protein tests — happen at every single prenatal visit throughout your first, second, and third trimesters. This ongoing monitoring is crucial because preeclampsia can develop at various stages of pregnancy. 

For those identified as high-risk in the first trimester, your provider might discuss preventative measures. Evidence suggests that taking low-dose aspirin (81mg) daily, typically from 12 to 28 weeks, can reduce the risk of preeclampsia by 20-30%. Additionally, for individuals in populations with low dietary calcium intake, calcium supplementation has been shown to reduce preeclampsia risk. These are choices you get to make in collaboration with your care team, much like discussing whether [Genetic Carrier Screening](/tests/genetic-carrier-screening) is right for you in early pregnancy.

Some centers, particularly in the UK and Europe, also use specific biomarkers like Placental Growth Factor (PlGF) and the sFlt-1 ratio for further risk stratification. While these are less commonly available in the US, it highlights the evolving nature of screening tools. It's always valuable to ask your provider about the screening methods available to you.

## What the results mean
A preeclampsia risk assessment doesn't give you a definitive 'yes' or 'no' diagnosis; instead, it helps your care team understand your likelihood of developing the condition. If your assessment indicates a higher risk, it opens the door for proactive discussions about potential interventions, such as starting low-dose aspirin. It also means your care team will be extra vigilant with your ongoing blood pressure and urine monitoring. 

It's important to remember that a higher risk doesn't mean you *will* develop preeclampsia, but it empowers you to make informed decisions about preventative strategies and to be aware of symptoms to watch for. This collaborative approach ensures you feel clear and confident in your care plan, similar to how an early [Cervical Length Ultrasound](/tests/cervical-length-ultrasound) provides information to guide specific care if needed.

## Questions worth asking
Having a calm and clear conversation with your provider about preeclampsia screening can bring immense clarity. Here are some questions you might consider asking:

*   "What factors in my personal history contribute to my preeclampsia risk assessment?"
*   "Are there any specific lifestyle adjustments or supportive measures we can explore to support my blood pressure?"
*   "What are the next steps if my risk assessment indicates a higher likelihood, and what are my options?"
*   "How will we continue to monitor for preeclampsia throughout my pregnancy, and what symptoms should I be aware of?"
*   "What resources are available if I want to learn more about preeclampsia and its management?"

Your provider is your best resource for your specific situation, and asking questions helps you feel grounded and empowered in your pregnancy journey.
