Defend: Advanced Immune Panel (Bioreference)

What this panel includes

• Reproductive hormones: Estradiol, progesterone, total and free testosterone

• Pituitary signaling: FSH and LH to assess hormonal regulation

• Hormone availability: SHBG to understand biologically active hormone levels

• Thyroid function: TSH, free T4, and free T3

• Autoimmune screening: ANA panel, CCP antibody, TPO antibodies and thyroglobulin antibodies

• Immune supporting micronutrient: Zinc and Vitamin D

• Prostate markers (when clinically appropriate): Total PSA and free PSA

Biomarkers tested

Why patients choose this

• One comprehensive draw that looks at reproductive hormones, pituitary signaling, thyroid, immune antibodies, and immune-supporting nutrients together.
• A more complete picture for those looking to understand immune health in the context of hormonal balance.
• Useful for individuals with suspected or known autoimmune conditions, chronic inflammatory symptoms, or thyroid concerns.
• Helpful for exploring patterns behind persistent symptoms like fatigue, brain fog, joint pain, or allergies.
• Schedule your lab test seamlessly and complete it at a lab near you.

Before your test

It is recommended to fast for at least 8 hours before your draw.

Important information

Why it matters: evaluating hormones, thyroid, immune antibodies, and key nutrients together offers insight into immune resilience and inflammatory burden.

Who it's for: especially useful for those with suspected or known autoimmune conditions, chronic inflammatory symptoms, thyroid concerns, or anyone seeking a more precise understanding of immune health alongside hormonal balance.
