Alzheimer's Disease

Alzheimer’s disease is a brain disorder that causes memory loss, thinking problems, and changes in daily function. A proactive plan starts by ruling out reversible causes of memory issues, then using Alzheimer’s-specific biomarkers if concern remains. Begin with basic blood tests (thyroid, vitamin B12, metabolic panel, complete blood count, A1c). If problems persist, add blood-based biomarkers that reflect Alzheimer’s biology—such as the amyloid beta (Aβ42/40) ratio and phosphorylated tau (p-tau)—often alongside neurofilament light (NfL) to gauge nerve-cell injury.

The Heavy Metals Random Urine Test Panel with Cadmium measures urinary levels of toxic metals including cadmium, lead, mercury, and arsenic to assess recent exposure. Elevated concentrations can result from occupational contact, contaminated water, diet, or environmental sources. This panel aids in detecting heavy metal toxicity, supporting evaluation of kidney stress, neurological health, and systemic metabolic effects.

Also Known As: Random Urine Heavy Metals Test with Cadmium

The Heavy Metals 24 Hour Urine Test Panel measures urinary excretion of arsenic, lead, and mercury to assess cumulative exposure. Collecting urine over a full day improves detection of toxic metal burden compared to random sampling. Elevated levels may reflect environmental contact, workplace exposure, or dietary intake, supporting evaluation of kidney function, neurological effects, and systemic health risks related to heavy metal toxicity.

One in nine people ages 65 and older and live in the United States have Alzheimer’s disease. This is more than 11% of the population, and the number is only growing.

Even though the prevalence of the disease and the population of elderly individuals is increasing, there still isn’t a cure for Alzheimer’s. Recent research studies are showing promise, but nothing is proven.

Therefore, anyone who thinks that they or a loved one may have the condition needs to get Alzheimer’s blood tests. These can help patients and their providers detect Alzheimer’s early, and this early diagnosis can slow the progression of the disease.

Keep reading if you're interested in learning more about how these blood tests can help Alzheimer's patients.

What Is Alzheimer’s Disease?

Alzheimer's disease is a progressive neurological disorder. Over time, the cells of the brain die, and the brain shrinks in size.
