Level 1 Ultrasound: An Overview for Patients

1. Introduction:

A Level 1 Ultrasound, also known as an Early Pregnancy Scan, is a routine ultrasound performed during the first trimester of pregnancy. It helps assess the early development of the fetus and detect any potential abnormalities.

2. Purpose:

A Level 1 Ultrasound is used to:

Confirm pregnancy and detect the fetal heartbeat.
Determine gestational age and expected due date.
Check for multiple pregnancies (twins, triplets, etc.).
Identify ectopic pregnancy or other complications.
Assess early fetal development and placental position.

3. Procedure:

The scan is performed using an abdominal ultrasound or a transvaginal ultrasound (if needed for better clarity).
A transducer is moved over the abdomen after applying a gel to obtain images.
The scan usually takes about 15–30 minutes.
It is a painless and safe procedure that uses sound waves instead of radiation.

4. Preparation:

A full bladder may be required for better imaging; you may be asked to drink water before the test.
Wear loose, comfortable clothing for easy access to the abdomen.
No fasting or special preparation is needed unless advised otherwise.

5. What to Expect During the Test:

You will lie on a table while the sonographer moves the probe over your abdomen.
If a transvaginal scan is needed, a small probe will be gently inserted into the vagina for a clearer view.
The doctor will examine the fetus's size, heartbeat, and early development.
Images may be shared with you during the scan.

6. After the Test:

Normal activities can be resumed immediately.
Results are usually available on the same day or within a short period.
Your doctor will discuss the findings and suggest any necessary follow-ups.

7. FAQs:

Is a Level 1 Ultrasound safe?
Yes, it is a completely safe and non-invasive test.
When is it performed?
Typically between 6–12 weeks of pregnancy.
Will it detect all abnormalities?
It helps in early assessment, but some conditions require later scans (e.g., Level 2 Ultrasound or anomaly scan).
Can I see the baby’s heartbeat?
Yes, fetal heart activity can usually be seen by 6–7 weeks.
