A handful of blood tests describe most of what is happening inside a healthy adult body. They show whether the blood is carrying oxygen the way it should, whether the kidneys and liver are clearing waste, how the body handles sugar and fat, and whether the thyroid and a few key vitamins sit in range. That core set applies to almost everyone. After that, biology splits, and men and women each have a short list worth adding.
Any Lab Test Now offers each of these as a direct-access test, with no doctor’s referral required. Running them is less about reacting to a problem and more about setting a baseline, because a single result means far more when there is a prior number to measure it against.
The Core Panel Every Adult Should Run
Six tests cover the ground that matters for most adults, regardless of sex. Each one looks at a different system, and together they catch the most common silent problems before symptoms show up.
- Complete blood count. A CBC measures red cells, white cells, hemoglobin, and platelets, which flags anemia, infection, and a range of blood disorders.
- Comprehensive metabolic panel. A CMP checks kidney and liver function, electrolytes, and blood sugar in a single draw.
- Cholesterol and lipids. A Cholesterol Lipid Panel reports the cholesterol and triglyceride numbers that drive long-term heart risk, and it is worth a baseline in your twenties.
- Blood sugar. A Fasting Glucose Test or a Hemoglobin A1C screens for prediabetes and diabetes, often years before symptoms.
- Thyroid. A TSH test checks the gland that sets metabolism, energy, and weight, and a Comprehensive Thyroid Panel digs deeper when something feels off.
- Vitamin D. Low vitamin D is one of the most common deficiencies in the country and shows up as fatigue, low mood, and weaker bones.
The simplest way to cover most of these at once is the Annual Check-Up Panel, and the general health hub lists the full menu of routine tests.
What Men Should Add
Two markers matter enough for men to track on their own line. Both change with age, and both are easy to check before they cause trouble.
- Testosterone. Levels fall by roughly one percent a year after about age 30, and the drop can quietly drain energy, libido, muscle, and mood. A Free and Total Testosterone Test shows where you stand.
- PSA. Prostate-specific antigen is the lab marker behind prostate cancer screening, a conversation that usually starts between 45 and 55 and earlier for Black men and those with a family history. The PSA blood test is available directly.
- Broader hormone health. When more than testosterone is in question, a Complete Hormone Health Panel gives the wider view.
What Women Should Add
Women carry a few risks that the core panel only partly covers, driven by menstruation, a higher rate of thyroid conditions, and cervical health.
- Iron status. Iron deficiency is the most common nutritional deficiency worldwide, and menstruating women are the group most likely to run low. A Ferritin Test measures iron stores, and an Anemia Panel gives the full picture.
- Thyroid. Women are several times more likely than men to develop a thyroid condition, so a Thyroid Panel earns its place on the list.
- HPV. Human papillomavirus is the main cause of cervical cancer, and HPV Testing is part of cervical screening from age 30.
- Hormones. For cycle changes, perimenopause, or symptoms of PCOS, a Complete Hormone Health Panel or a Comprehensive Women’s Wellness Panel covers the relevant markers.
How Often to Repeat Them
Most of the core panel is worth running once a year, since the value lives in the trend rather than any single reading. A few have their own rhythm.
- Cholesterol every four to six years at average risk, and yearly when risk factors are present.
- Blood sugar every three years from age 35, sooner with weight or family-history risk.
- Thyroid and vitamin D when symptoms appear or while on treatment, rather than on a fixed clock.
- Testosterone and other hormones when symptoms prompt the first test, then periodically to track the response.
The Case for a Baseline
One lab result is a snapshot. The same tests run year after year are a story, and the story is where early signals live, a slow climb in blood sugar or a steady slide in iron that no single reading would catch. Direct-access testing makes that easy to keep up on your own schedule. The men’s and women’s wellness panels bundle most of the sex-specific markers, the Annual Check-Up Panel covers the core, and the lab testing FAQ walks through how results and timing work.
