Estrogen Receptor Immunostain, Technical Component Only
Use
This test is used for the qualitative detection of estrogen receptor alpha protein in a diagnostic setting. Estrogen receptor alpha protein expression is limited to normal and neoplastic tissues related to the reproductive system such as breast, cervix, endometrium, uterus, ovary, and prostate. The test helps in assessing the presence of this protein, which can be critical for diagnosis and management of certain types of cancers.
Special Instructions
Not provided.
Limitations
This test does not include pathologist interpretation, only technical performance of the stain. If interpretation is required, order PATHC for a full diagnostic evaluation or second opinion. The age of a cut paraffin section can affect immunoreactivity, and stability thresholds vary widely. The charge of glass slides can be affected by environmental factors, potentially altering stain results. Best practices for storage include minimizing time stored after unpackaging and limiting exposure to high humidity and heat.
