What are Hormonal Assays?
Our laboratory performs a range of Hormonal Assays to measure hormone levels in blood and help doctors evaluate endocrine, reproductive and metabolic health.
Hormonal assays are laboratory tests used to measure specific hormones present in the blood. Hormones are chemical messengers that regulate important body functions including growth, metabolism, reproduction, menstrual cycles, thyroid activity and stress responses. Measuring hormone levels can help doctors identify hormonal imbalances and support the diagnosis and monitoring of various endocrine and reproductive conditions.
Common Hormonal Assays
- • Thyroid Profile — T3, T4 and TSH.
- • Free T3 (FT3) and Free T4 (FT4).
- • FSH (Follicle-Stimulating Hormone).
- • LH (Luteinizing Hormone).
- • Prolactin.
- • Estradiol (E2).
- • Progesterone.
- • Testosterone — Total and Free, where applicable.
- • Cortisol.
- • Insulin.
- • Vitamin D and other related endocrine markers.
Why are Hormonal Assays performed?
Hormonal tests may be recommended by a doctor to evaluate hormone production, identify imbalances or monitor an existing condition. They are commonly used to:
- • Evaluate thyroid function and thyroid disorders.
- • Investigate menstrual irregularities and reproductive health.
- • Support evaluation of fertility in men and women.
- • Assess symptoms related to hormonal imbalance.
- • Evaluate abnormal levels of reproductive hormones.
- • Monitor certain endocrine and hormonal conditions.
- • Assess blood glucose and insulin-related conditions.
- • Support evaluation of adrenal and metabolic function.
How to prepare for Hormonal Assays
Preparation depends on the hormone being tested and the reason for testing. Some hormonal tests can be performed at any time, while others may need to be collected at a specific time of day or at a particular stage of the menstrual cycle.
Certain tests may require fasting, while others may be affected by medications, supplements, physical activity or recent meals. If you are taking any medication or hormone therapy, inform your doctor and the laboratory team before sample collection. Follow the specific instructions provided for your test to ensure accurate results.
FAQs
Do I need to fast for a hormonal test?
Not all hormonal tests require fasting. The requirement depends on the specific hormone or panel being tested. Please follow the instructions provided by your doctor or laboratory.
Does the timing of the test matter?
Yes. Some hormones naturally change during the day or throughout the menstrual cycle. Your doctor may therefore recommend a specific time or day for sample collection.
How is the hormone sample collected?
Most hormonal assays are performed using a small blood sample collected from a vein in the arm by a trained phlebotomist. The procedure usually takes only a few minutes.
Can medications affect hormone test results?
Yes. Certain medicines, supplements and hormone therapies can influence hormone levels. Inform your doctor and laboratory team about any medications you are taking before the test. Do not stop prescribed medication unless advised by your doctor.
When will my hormonal assay report be ready?
Report availability depends on the specific hormone test and laboratory processing requirements. Many routine tests are available within the same day, while some specialized assays may require additional processing time.
