  Sleep disturbance is a common problem affecting millions of people worldwide. A variety of factors, such as stress, anxiety, depression, and certain medical conditions, can cause it. However, sleep is crucial for overall health and well-being, and when we don't get enough quality sleep, it can lead to several adverse health consequences. One potential solution for sleep disturbance is a hormone sleep test. This type of test measures the levels of various hormones in your body that can impact sleep, such as melatonin, cortisol, and testosterone. By identifying any imbalances or deficiencies in these hormones, a hormone sleep test...

As men age, they may experience a decline in testosterone levels which can lead to a range of symptoms commonly referred to as male menopause or andropause. This condition is not as well-known as female menopause, but it can have a significant impact on a man's quality of life.

Acne is a common skin condition that affects millions of people worldwide, regardless of age or gender. While there are several treatment options available, the root cause of acne often lies in hormonal imbalances. Saliva hormone testing is an emerging diagnostic tool that can help identify these imbalances and guide more targeted treatment options. Hormonal imbalances, particularly in androgens like testosterone, have been implicated in the development of acne. These hormones can increase sebum production, leading to clogged pores and the growth of acne-causing bacteria. Saliva hormone testing allows for the measurement of these hormones in a non-invasive and convenient...

In this blog, we will explore the benefits of neurotransmitter testing and how it can help improve our mental health and well-being. Accurate Diagnosis: A neurotransmitter test can accurately diagnose the underlying...

By Margaret N Groves, M.Phil, ELS Two vitamin D studies were published recently, both utilising ZRT's testing in dried blood spots. Dried blood spot samples are well suited for research applications because they are equivalent to serum but have the advantage of the ease of sample collection, shipping, and storage, which doesn’t require any refrigeration or biohazard labeling. Also, samples are easily identified by details that can simply be written on the outside flap of the collection cards, which require minimal freezer space for long-term storage of samples. Here are brief summaries of each study: Wakayo T, Belachew T, Vatanparast H,...
