Ordering the Rhythm Plus | Genova Diagnostics Diagnostics
Ordering the Rhythm Plus | Genova Diagnostics Diagnostics helps track hormone patterns over a full day, giving a clear picture of how estrogen, progesterone, testosterone, cortisol, DHEA, and melatonin change over time. This test uses multiple saliva samples to show how these hormones shift, which can help explain symptoms like fatigue, mood changes, or trouble sleeping. Interestingly, this test can also reveal hidden hormone imbalances that may not show up in a single blood draw, making it useful for people with symptoms that come and go.
When ordering the Rhythm Plus | Genova Diagnostics Diagnostics, you can expect these specific benefits:
- Shows how your hormones change throughout the day and night, not just at one moment.
- Helps find patterns linked to sleep problems, energy dips, or mood swings.
- Uses a simple saliva collection kit you can use at home, making it easy and comfortable.
- Gives detailed results for estrogen, progesterone, testosterone, cortisol, DHEA, and melatonin.
- Supports your doctor in making targeted treatment plans based on your unique hormone patterns.
Who Should Consider Hormone and Cortisol Pattern Testing
People who feel tired in the morning but wired at night, or who notice their mood and energy change during the day, may benefit from this test. For example, someone who wakes up feeling exhausted, struggles with focus at work, and then has trouble falling asleep at night could use this test to find out if hormone shifts are part of the problem.
Ordering this test may also be helpful in these situations:
- People with ongoing digestive issues that seem to get worse at certain times of day.
- Those who have headaches or migraines that follow a daily pattern.
- Anyone with skin rashes that flare up in the evening or after stressful events.
- People who notice joint pain or stiffness that changes with their sleep or stress levels.
- Someone who has tried changing their diet or exercise but still feels tired or moody, which can sometimes be linked to hormone cycles.
Testing for hormone and cortisol patterns can help explain why symptoms like fatigue, mood swings, or sleep problems keep coming back, even after trying other solutions. Delaying this test could mean missing the chance to spot hormone changes early, which might make it harder to find the right treatment plan later.
