Dumont Tel (519) 681-8731 ## 18. 510 K Summary This summary of 510(K) safety and effectiveness information is being submitted in accordance with the requirements of SMDA 1990 and 21 CFR 807.92 1. The assigned 510K number is KO14120 2. The classification name of the device: enzyme immunoassay for testosterone 3. Classification number 862.1680 - 4. Proprietary name: Testosterone By Enzymeimmunoassay (EiA) Class I - 5. Use of the device Direct determination of Testosterone (total) by enzymeimmunoassay (Elisa) in human serum - 6. The predicate device's name and address of which we claim equivalence: Diagnostics System Laboratories,(DSL) 445 Medical Center Blvd. Webster, Texas, 77598 DSL 10-4000 Active™ Testosterone Enzymeimmunoassay (EiA) kit 510(K) #971823 {1}------------------------------------------------ 7. The Testosterone (total) Elisa kit consists of one polyclonal antibody which is coated on microtiter plate (96 wells per kit). The antigen Testosterone 3 carboxymethyl oxime is conjugated to an enzyme namely horse radish peroxidase. The standards are prepared from protein base matrix and all other reagents within a kit namely assay buffer, wash buffer concentrate, substrate tetramethytbenzidine (TMB) and stopping solution. The incubation time is 60 minutes at room temperature. 25 ul of patient serum , control serum and each standard are added for each assay. After incubation the plates are washed 3 times, each time with 300 ul of diluted wash buffer. The plates are dried. 150 ul of TMB is added to each well and allowed to incubate for 10 - 15 minutes. 50 ul of stopping solution is added into each well and the colour becomes yellow. The plate is read within 20 minutes in a microtiter plate reader at 450 mm. 9. Substantial equivalence: 1. The dbc In-vitro diagnostic device namely Testosterone (total) by enzymeimmunoassay (EiA) has the same intended use as current device on the market referred to "predicate device". 2. The dbc In-vitro diagnostic device namely Testosterone (total) by enzymeimmunoassay (EiA) has the same technological characteristics as predicate device namely Enzymeimmunoassay (EiA) antigen/antibody. 3. The dbc enzymeimmunoassay for total testosterone has no new technological feature which will raise questions of safety and effectiveness. 4. The data obtained help to indicate substantial equivalency and the results of a number of human serum samples. The results need not be exactly the same but a collaboration of equivalence is necessary in this case r=0.958. 5. The dbc total testosterone safety and effectiveness compared to the predicate devices can be found in our results of performance characteristics namely, sensitivity, specificity, Intra and Inter assay precision, Recovery and Linearity. {2}------------------------------------------------ 6. dbc total testosterone intended use, methodology, reagents and materials including equipments and control necessary to perform the test are similar to the predicate device. From our assay data and protocol the safety and effectiveness of dbc total testosterone is similar to the predicate device. 7. Our 510K presentation demonstrates substantial equivalence to predicate device in regards: - intended use - design - performance - material and equipments - safety - effectiveness - standards - control {3}------------------------------------------------ Image /page/3/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services. The logo consists of a circular seal with the text "DEPARTMENT OF HEALTH & HUMAN SERVICES - USA" around the perimeter. Inside the circle is an abstract symbol resembling three stylized birds in flight, stacked vertically. The birds are depicted in black and have a flowing, wave-like design.
