Ultrasound Pelvis (TAS), in Visit Clinic

USG pelvis TAS is a transabdominal pelvic ultrasound — a noninvasive imaging test using sound waves through the lower abdomen to visualize pelvic organs such as the uterus, ovaries, bladder, and prostate/seminal vesicles in men. It evaluates pelvic pain, abnormal bleeding, masses, pregnancy, cysts, and urinary problems. A full bladder improves visualization; no radiation is involved.

TAS (transabdominal scan or transabdominal sonography) is an external ultrasound performed by moving a probe across the abdomen to image pelvic organs or the fetus. It gives a broad field-of-view, is noninvasive and safe, and often requires a full bladder for better visualization. TAS is commonly used in obstetrics and gynecology and may be paired with transvaginal scans for finer detail.

A transabdominal (TAS) ultrasound is usually painless. Most people feel only mild discomfort from a full bladder or from probe pressure over tender areas. It’s non‑invasive and doesn’t cause lasting pain. If you experience significant pain during the scan, tell the technician so they can stop, adjust the exam, and assess for any underlying issue.

Yes. A transabdominal ultrasound (TAS) can detect an intrauterine pregnancy, typically showing the gestational sac and embryo reliably from about 6 weeks; a fetal heartbeat is usually seen by 6–7 weeks. For very early pregnancy (4–5 weeks) or when clearer imaging is needed, a transvaginal ultrasound is more sensitive. If unclear, repeat or use transvaginal scanning.

TAS stands for Total Antioxidant Status. The TAS test measures the overall antioxidant capacity of blood or serum, reflecting the combined action of enzymatic and non‑enzymatic antioxidants. It is used to evaluate oxidative stress, monitor antioxidant therapy, or assess disease states linked to imbalance between free radicals and antioxidant defenses. Results inform clinical assessment and research.

Yes. For a transabdominal pelvic ultrasound you should drink water to fill your bladder (commonly about 750–1,000 mL or roughly 32 ounces) about an hour before the exam and avoid urinating until after imaging. For a transvaginal scan you’re usually asked to come with an empty bladder. If you have fluid restrictions, diabetes, or uncertainty, contact the imaging center.
