The ZRT Laboratory CardioMetabolic Profile is a convenient finger-prick blood test designed to detect early warning signs of diabetes and cardiovascular disease. By measuring key markers such as insulin, cholesterol, triglycerides, HbA1c, and inflammation, it provides a comprehensive view of heart and metabolic health, supporting early intervention and personalized preventive care.

PCOS and insulin resistance are two of the biggest yet most misunderstood barriers to fertility. This guide explains how fertility mapping helps uncover hidden hormone patterns, ovulation issues, and metabolic imbalances—empowering women with PCOS to take a smarter, more targeted approach to conception and long-term hormonal health.

A fasting insulin test helps identify early signs of insulin resistance, often before blood sugar levels become abnormal. By measuring insulin after an overnight fast, it provides valuable insight into metabolic health, energy balance, and long-term risks such as diabetes and heart disease. Easy at-home testing with a simple finger-prick sample allows you to understand your insulin levels clearly and take proactive steps to protect your health.

Title: Understanding CardioMetabolic Risk – A Silent Threat We Can’t Ignore The rise in cardiovascular disease (CVD), obesity, and type 2 diabetes (DM2) is one of the most pressing health concerns of our time. CVD remains the leading cause of death for both men and women in the United States. Alarmingly, obesity and insulin resistance—precursors to DM2—significantly increase the risk of developing CVD. Yet, these conditions are largely preventable with early detection and lifestyle changes. So, how can we spot the danger before it's too late? What is CardioMetabolic Risk? Cardiometabolic risk refers to a cluster of modifiable risk factors...

Fertility Mapping: Navigating Fertility with PCOS and Insulin Resistance (Part II)By Dr. Alison McAllister Polycystic Ovary Syndrome (PCOS) is a complex, multifactorial condition influenced by disruptions in hormone receptors, metabolism, neurotransmitter function, and nutrient balance. As a lifelong disorder, PCOS is a leading contributor to infertility, weight gain, and an increased risk for cardiometabolic issues. In this blog post, we dive deeper into laboratory testing, helping healthcare providers understand which tests are critical for women suspected of having PCOS. Lab Testing for PCOS PCOS is most commonly diagnosed through the Rotterdam Criteria, a diagnostic framework that considers various indicators, including...
