read moreIndications: Beta-carotene is a vibrant red-orange pigment found in abundance in many fruits and vegetables, particularly those with yellow or orange colouring. It is a member of the carotenoid family, a group of naturally occurring compounds that play crucial roles in human health. Beta-carotene is a provitamin A, meaning that the body can convert it…
read moreIndications: Riboflavin (vitamin B2) is the key building block for its co-enzymatic forms flavin adenine dinucleotide (FAD) and flavin mononucleotide (FMN), of which FAD is the main form in body tissues. FAD levels are a reliable way of assessing vitamin B2 status and are reported in our results. Vitamin B2 is required for carbohydrate, lipid…
read moreIndications: Our niacin (vitamin B3) test includes levels of niacinamide, nicotinic acid, nicotinamide and the total vitamin B3 level (as NAD). Vitamin B3 is required as a co-enzyme in electron-transfer reactions (catabolism of carbohydrates, fats, proteins, and alcohol), also as a substrate for NAD-consuming enzymes (ADP-ribosylation, NAD-dependent deacetylation, calcium mobilization) and as a ligand (inhibitory…

read moreIndication: Vitamin B6 describes a group of six water-soluble vitamins with vitamin B6 activity. We report vitamin B6 (Pyridoxal-5-phosphate) as the most biologically active form of the vitamin and is recommended for assessing nutritional B6 status. Vitamin B6 is required for energy production, nervous system, haemoglobin synthesis and function, the folate and methylation cycles, hormone…
read moreIndications: Raised in tumoral calcinosis, primary hyperparathyroidism, idopathic hypercalciuria and scarcoidosis as well as normal growing children and pregnant lactating females. Depressed in chronic renal failure, vitamin D dependent rickets, pseudohypoparathyroidism and tumor induced osteomalacia. This is the preferred test for vitamin D levels (also known as 25-hydroxyvitamin D). Sample Collection Instructions (finger-prick option): Vitamin…
read moreIndications: Deficiency may be associated with haemolytic anaemia and with neurological disturbance and has been observed very rarely in premature infants, chronic cholestasis and malabsorption. Vitamin E is an antioxidant and dietary supplementation is widely used in regimes aimed at reducing atherosclerosis.

read moreIndications: There are a number of structurally similar, naturally occurring compounds which have vitamin K activity. The major plant form is phylloquinone (vitamin K1). The menaquinones (vitamins K2, also referred to as MK) are predominately of bacterial origin. In the typical Western diet, K1 and MK account for 90% and 10% of the vitamin K…
read moreIndications: Biotin (coenzyme R, vitamin H) is an essential micronutrient for all mammals and is a water-soluble member of the B complex group of vitamins. It has an essential role in the metabolic pathways of gluconeogenesis, fatty acid synthesis and the metabolism of amino acids . Biotinylation of histones appears to be important in embryological…
