Understanding Lab Tests for Rhabdomyosarcoma
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Rhabdomyosarcoma is a rare type of soft tissue sarcoma that primarily affects children and adolescents. The diagnosis of rhabdomyosarcoma is typically made through imaging studies and tissue biopsy rather than blood tests. However, certain blood markers can provide valuable information for monitoring tumor activity and guiding treatment decisions.
Recommended Test
IGF-2
This test measures insulin-like growth factor 2 levels in the blood. Rhabdomyosarcoma tumors frequently show overexpression of IGF-2, which can drive tumor growth and progression. Monitoring IGF-2 levels may help assess tumor activity and treatment response in patients with this rare sarcoma.

The Role of Blood Testing in Rhabdomyosarcoma
While there isn't a single blood test to diagnose rhabdomyosarcoma, laboratory testing is fundamental for assessing tumor markers that may be elevated in this condition. These tests help healthcare providers monitor disease progression, evaluate treatment response, and make informed decisions about ongoing care.
Understanding Your Results
Elevated IGF-2 levels may indicate increased tumor activity, but results must always be interpreted in the context of other clinical findings, imaging studies, and pathology reports. Your healthcare team will use this information alongside other diagnostic tools to develop the most appropriate treatment plan.
