It is understandable that you are concerned about your menstrual irregularities, especially given your medical history of endometriosis and adenomyosis. Your desire to investigate the underlying causes through blood tests, particularly for pituitary function, is both reasonable and proactive.
In general, the pituitary gland plays a crucial role in regulating various hormones that affect the menstrual cycle. Hormones such as Follicle Stimulating Hormone (FSH) and Luteinizing Hormone (LH), which are produced by the pituitary gland, are essential for normal ovarian function. If there is a dysfunction in the pituitary gland, it can lead to irregularities in these hormones, which may subsequently affect your menstrual cycle.

You have the right to request specific blood tests from your healthcare provider. It is important to communicate your concerns clearly. You can express that you are experiencing significant menstrual irregularities and that you would like to rule out any potential issues with your pituitary function. A good healthcare provider will take your concerns seriously and may agree to perform the tests if they deem it necessary.
If your doctor is hesitant to order these tests, you can ask for an explanation. Sometimes, doctors may have reasons for not ordering certain tests based on their clinical judgment, but it is your health, and you deserve to be informed. If you feel that your concerns are not being adequately addressed, you may consider seeking a second opinion from another gynecologist or an endocrinologist, who specializes in hormonal issues.

Regarding the option of getting the tests done independently, it is possible to have blood tests conducted at various laboratories without a doctor's order, depending on the regulations in your area. However, it is advisable to consult with a healthcare professional before doing so. They can provide guidance on which specific tests would be most relevant for your situation and help interpret the results accurately.
In terms of what tests might be relevant, you may want to consider asking for the following:
1. FSH and LH Levels: To assess the function of the pituitary gland and its impact on ovarian function.

2. Prolactin Levels: Elevated prolactin can interfere with menstrual cycles and may indicate a pituitary issue.

3. Thyroid Function Tests: Thyroid hormones can also affect menstrual cycles, so checking TSH, Free T4, and Free T3 levels can be beneficial.

4. Estradiol and Progesterone Levels: These hormones can provide insight into ovarian function and the menstrual cycle.

In conclusion, you absolutely can request blood tests for pituitary function and other hormonal evaluations. It is essential to advocate for your health and ensure that your concerns are addressed. If you encounter resistance from your current healthcare provider, do not hesitate to seek a second opinion or explore independent testing options. Your menstrual health is important, and understanding the underlying causes can help you make informed decisions about your treatment and management moving forward.
