The frequency of hormone level monitoring for a trans person taking HRT will depend on several factors, including the type of hormone therapy, the dose, and the individual's medical history.
In general, it is recommended that hormone levels are checked at least every three to six months during the first year of HRT, and then every six to twelve months thereafter.
However, your healthcare provider may recommend more frequent monitoring if there are concerns about hormone levels, side effects, or other pre-existing medical issues. It's important to work closely with your healthcare provider to develop a monitoring plan that is tailored to your individual needs and circumstances.
Monitoring hormone levels is important to ensure that the gender-affirming HRT is effective in achieving your desired changes, and to identify any potential complications or side effects that may require adjustments to your medication plan. Your healthcare provider may measure levels of estradiol (for trans feminine folks) or testosterone (for trans masculine folks) and other hormone-related markers in your blood to evaluate the effectiveness of the HRT and to monitor for potential complications.
