The Aldosterone/Direct Renin Ratio (ADRR) is a vital screening tool used by clinicians to detect primary aldosteronism, a leading cause of secondary high blood pressure.

Aldosterone is a hormone that regulates sodium and water balance, while renin is an enzyme that controls aldosterone production. In a healthy body, these two work in tandem. However, in primary aldosteronism, the adrenal glands overproduce aldosterone independently of renin.

By measuring both levels in the blood and calculating the ratio, doctors can identify an abnormal imbalance—specifically, highly elevated aldosterone alongside suppressed renin levels—signaling the need for further diagnostic testing.

Alkaline Phosphatase (ALP) is an essential enzyme found throughout the body, with the highest concentrations located in the liver, bones, kidneys, and digestive tract. It plays a critical role in breaking down proteins and aiding bone mineralization.

A standard ALP blood test is widely used to evaluate liver function and detect bone disorders. Elevated ALP levels often signal blocked bile ducts, liver disease, or rapid bone turnover, which can occur in conditions like Paget's disease or healing fractures. Conversely, low levels are less common but can indicate malnutrition or a rare genetic disorder called hypophosphatasia.

An Alkaline Phosphatase (ALP) Isoenzymes Electrophoresis Serum test is a diagnostic tool used to determine the specific source of elevated ALP levels in the blood. Because ALP is produced by several organs—mainly the liver, bone, intestine, and placenta—a standard test cannot pinpoint which tissue is damaged.

Electrophoresis solves this by using an electric current to separate these distinct forms (isoenzymes) based on their physical properties. Identifying which specific isoenzyme is elevated allows clinicians to distinguish between liver disease (like blocked bile ducts) and bone disorders (like Paget's disease), ensuring a precise diagnosis and targeted treatment plan.

An Egg White (Anda) Individual Food Allergen test is a specific blood test used to detect an allergic sensitivity to proteins found in egg whites. Egg allergy is one of the most common food allergies, particularly in children. While both the yolk and the white contain proteins, the white is typically the primary trigger for allergic reactions.

The test measures the level of specific IgE antibodies produced by the immune system in response to egg white exposure. A positive result helps clinicians diagnose the allergy, allowing individuals to manage symptoms by avoiding egg-containing products and preventing potential reactions like hives, digestive distress, or anaphylaxis.

An Egg Yolk (Anda) Individual Food Allergen test is a specific blood diagnostic tool used to identify allergic sensitivity to the proteins contained within egg yolks. Although egg whites are more commonly associated with allergic reactions, the yolk also contains distinct proteins that can trigger an inappropriate immune response.

The test measures the concentration of specific IgE antibodies in the serum produced against egg yolk proteins. Identifying an egg yolk allergy helps healthcare providers create tailored dietary management plans, helping individuals safely avoid trigger foods and prevent allergic symptoms ranging from mild hives and gastrointestinal discomfort to severe anaphylaxis.
