 After nearly 30 years in in the production and development of haptens for patch testing, we work in close cooperation with dermatologists practising clinical and experimental patch testing. By cooperating with national contact dermatitis groups in various countries we want to meet the needs specific to different regions. We are guided by national groups such as NACDG and the international group International Contact Dermatitis Research Group (ICDRG) as well as European Environmental and Contact Dermatitis Research Group (EECDRG). With this in mind we believe ourselves to be as up to date as possible and able to facilitate dermatological investigations where patch tests are involved.Our aim is not only to provide dermatologists with the necessary haptens and Test Chambers for patch testing, but also to actively take part in the development and selection of haptens, with special emphasis in the field of occupational dermatology. Our work is also focused on the standardization of patch test haptens and development of new methods and medical devices. Our striving towards these goals is facilitated by the fact that we specialize in, and only work with, products in the field of diagnostic patch testing and contact allergy. 
Chemotechnique Diagnostics offers three types of test chambers; IQ Chambers, IQ Ultra® Chambers and IQ Ultimate® Chambers. The IQ Ultra® Chambers and IQ Ultimate® Chambers combine the advantages of using inert square polyethylene foam chambers attached to a hypoallergenic tape (IQ Ultra®) or a water resistant, elastic, transparent thin polyurethane film (IQ Ultimate®). All test units offers the feature of reattaching the tape to a stiff plastic cover to prepare test units in advance. For easy and fast loading of the test chambers use our Application Device. |
Chemotechnique Diagnostics takes pleasure in offering the widest range of commercially available haptens for patch testing now expanded to cover more than 500 different preparations.. In cooperation with various national Contact Dermatitis Research Groups a number of country specific Standard Series are available in addition to our normal range. The products are available through our extensive network of distributors worldwide. You may download our electronic catalogue in Adobe format from our web site
. Patch testing, being the classical method for the diagnosis of contact allergies, is an important tool when investigating contact dermatitis. This test becomes more reliable when using high quality standardised test substances. It is also important that the testing and interpretation of the result is performed by an experienced physician.The raw material used is of the highest purity and treated so that extremely small particles are formed and incorporated in the white petrolatum used as a vehicle. The substances with a petrolatum vehicle are supplied in 5 ml polypropylene syringes, while those in a liquid solution are supplied in 8 ml polypropylene dropper bottles. Haptens used infrequently should be stored in a cool place protected from light. In accordance with their stability, we recommend that all substances should be renewed according to the expiry stated on the labels of the haptens. The white petrolatum used as a vehicle is from Penreco. As a rule, we produce the purest and most homogeneous contamination-free haptens. We also provide a special Skin Marker for marking the patch test site. This convenient marker contains Methylrosaniline and Silvernitrate for prolonged staining of the skin. For dark skin types or when a non staining ink is required we offer a UV Skin Marker. We also produce a Nickel Spot Test (Dimethylglyoxime) for detection of free Nickel in metal objects. |
