Understanding the Most Common Blood Tests at Members Medical Spa
At Members Medical Spa, we take a comprehensive approach to your health and wellness. Blood testing is one of our most important tools for uncovering what’s happening inside your body—whether you’re feeling fatigued, struggling with hormonal imbalances, or simply optimizing your overall well-being. Below are some of the most common blood tests we perform and what they reveal about your health:
1. CMP (Comprehensive Metabolic Panel)
This test checks key markers of metabolism and organ function, including blood sugar, electrolytes, kidney function, and liver enzymes. It gives a broad snapshot of your internal balance and overall metabolic health.
2. CBC (Complete Blood Count)
The CBC measures your red and white blood cells, hemoglobin, hematocrit, and platelets. It helps detect signs of anemia, infection, inflammation, and even certain deficiencies or blood disorders.
3. Hypothyroid Panel
This panel includes thyroid hormones and other markers that assess whether your thyroid is underactive—a common cause of fatigue, weight gain, hair thinning, and mood changes.
4. Cortisol
Cortisol is your main stress hormone. Elevated or low levels can indicate adrenal fatigue, chronic stress, or issues with your body’s stress-response system. It’s a key marker in understanding energy levels, sleep, and weight gain.
5. Ferritin
Ferritin measures your body’s iron stores. Low levels often suggest iron deficiency (even before it shows up in other tests), which can lead to fatigue, hair loss, or weakness. Too much ferritin can signal inflammation or other issues.
6. FSH (Follicle-Stimulating Hormone)
FSH helps regulate the menstrual cycle and egg production in women, and sperm production in men. Abnormal levels can be a sign of menopause, fertility issues, or hormone imbalances.
7. Insulin
Insulin is the hormone that regulates your blood sugar. Elevated fasting insulin can indicate insulin resistance, a common root cause of weight gain, fatigue, and increased risk for metabolic conditions like type 2 diabetes and PCOS. Monitoring insulin helps us personalize your nutrition, lifestyle, and wellness plan.
8. Prolactin
Prolactin is most known for its role in breast milk production, but it also affects reproductive health in both women and men. High prolactin levels can interfere with ovulation, libido, and fertility. It’s also commonly evaluated when there are signs of hormonal imbalance or irregular cycles.
9. Estrogen
Estrogen is a key hormone in female reproductive health, but it also plays a role in mood, skin, bone density, and heart health. Whether levels are too high or too low, estrogen imbalances can lead to symptoms like irregular periods, hot flashes, or weight changes.
10. Progesterone
Progesterone helps regulate the menstrual cycle and supports pregnancy. We often check this hormone to determine whether you’re ovulating properly or to investigate symptoms like PMS, cycle irregularities, or difficulty conceiving.
11. LH (Luteinizing Hormone)
LH plays a critical role in ovulation and reproductive function. We use LH testing to assess fertility issues, determine where you are in your menstrual cycle, or help diagnose conditions like PCOS.
12. TSH (Thyroid-Stimulating Hormone)
TSH is the master controller of your thyroid. It signals your thyroid gland to produce hormones that regulate metabolism, energy, and body temperature. An elevated or low TSH can be an early sign of thyroid dysfunction, both of which can affect your energy, metabolism, weight, and mood.
13. T3 and T4 (Thyroid Hormones)
These are the active thyroid hormones responsible for keeping your metabolism running smoothly. T3 (triiodothyronine) and T4 (thyroxine) testing gives us more detail about how well your thyroid is functioning, and whether your symptoms could be due to hypothyroidism or hyperthyroidism.
14. Vitamin D
Vitamin D is essential for immune support, bone health, and mood regulation.
Low levels are extremely common, especially in people who spend a lot of time indoors or live in less sunny climates. Deficiency can contribute to fatigue, depression, weakened immunity, and even hormone disruption.
15. Vitamin B (Especially B12 and Folate)
Vitamin B levels—especially B12 and folate—are essential for energy, brain function, red blood cell production, and nervous system health. Low levels can cause fatigue, brain fog, mood changes, and even numbness or tingling in the hands and feet.
