INTRODUCTION
Reference Standard: Progesterone diluted in human Progesterone is a C21 steroid which is synthesised from both tissue and circulating cholesterol. Cholesterol is transformed to pregnenolone which is Level as stated on vial
then converted via a combined dehydrogenase and isomerase to Known level of Progesterone diluted in human progesterone. The principle production sites are the adrenals and ovaries and the placenta during pregnancy. The majority of this steroid is Level as stated on vial
metabolised in the liver to pregnanediol and conjugated as a glucuronide Known level of Progesterone diluted in human Progesterone exhibits a wide variety of end organ effects. The primary role Progesterone
of progesterone is exhibited by the reproductive organs. In males, Rabbit anti Progesterone reagent. Ready to use progesterone is a necessary intermediate for the production of cortcosteroids and androgens. In females, progesterone remains relatively constant throughout the follicular phase of the menstrual cycle. The Progesterone conjugated to Horseradish Peroxidase. concentration then increases rapidly following ovulation and remains elevated for 4-6 days and decreases to the initial level 24 hours before the onset of menstruation. In pregnancy, placental progesterone production Phosphate based buffer containing stabilising rises steadily to levels of 10 to 20 times those of the luteal phase peak. Progesterone measurements are thus performed to determine ovulation as well as to characterise luteal phase defects. Monitoring of progesterone Substrate Solution: 3,3’, 5,5’ Tetramethyl Benzidine therapy and early stage pregnancy evaluations comprise the remaining uses in a citrate buffer. Ready to use.

PRINCIPLE OF THE TEST
Micropipettes: 100μl, 200μl, 1000μl and 5000μl Disposable pipette tips The PATHOZYME PROGESTERONE is based on the principle of
Microplate reader fitted with a 450nm filter competitive binding between Progesterone in the test specimen and Progesterone-HRP Conjugate for a constant amount of rabbit anti- Progesterone. In the incubation, goat anti-rabbit IgG-coated wells are incubated with Progesterone standards, controls, patient samples, Progesterone-HRP Conjugate Reagent and rabbit anti-Progesterone PRECAUTIONS
Reagent. During the incubation, a fixed amount of HRP-labelled Progesterone competes with the endogenous Progesterone in the standard PATHOZYME PROGESTERONE contains materials of human origin

Thus, the amount of Progesterone antibodies and HBsAg by FDA approved methods at single donor peroxidase conjugate immunologically bound to the well progressively level. Because no test can offer complete assurance that products decreases as the concentration of Progesterone in the specimen increases. derived from human source will not transmit infectious agents it is Unbound Progesterone peroxidase conjugate is then removed and the wells recommended that the reagents within this kit be handled with due washed. The Substrate (TMB) is then added, resulting in the development of care and attention during use and disposal. All reagents should, blue colour.

The intensity of the colour formed is proportional to the amount of enzyme present and is inversely related to the amount of unlabelled Progesterone in PATHOZYME PROGESTERONE Reagents do not contain dangerous

TROUBLESHOOTING
For use by operatives with at least a minimum of basic laboratory Obtain a sample of venous blood from the patient and allow a clot to form and retract. Centrifuge clotted blood sample and collect clear serum. Fresh Do not use damaged or contaminated kit components. Use a separate disposable tip for each sample to prevent cross Obtain a sample of venous blood from the patient and add to EDTA blood collection vial. Centrifuge sample and collect clear plasma. Fresh plasma Duplication of all standards and specimens, although not required, is Do not use haemolysed, contaminated or lipaemic serum or plasma for testing as this will adversly affect the results. Specimens and standards should be run at the same time to keep Serum or plasma may be stored at 2oC to 8oC for up to 48 hours prior to testing. If longer storage is required, store at –20oC for up to 1 year. It is recommended that no more than 32 wells be used for each assay Thawed samples must be mixed prior to testing. run if manual pipetting is used, since pipetting of all Standards and specimens should be completed within 3 minutes. A full plate of 96 Do not use Sodium Azide as a preservative as this may inhibit the wells may be used if automated pipetting is available. Replace caps on all reagents immediately after use. Do not repeatedly freeze-thaw the specimens as this will cause false results. Avoid repeated pipetting from stock reagents as this is likely to cause REAGENT PREPARATION
Do not mix reagents or antibody coated strips from different kits. All reagents should be brought to room temperature (20oC to 25oC) and When dispensing, care should be taken not to touch the surface of the mixed gently prior to use. Do not induce foaming. Working Solution: Dilute the concentrated conjugate using 1 part conjugate Do not allow reagent to run down the sides of the well. Prior to the to 10 parts conjugate diluent ( 1/11 dilution ) 100μl is required per well. start of the assay bring all reagents to room temperature (20oC to Diluted reagent is stable at 2oC to 8oC for one month. 25oC). Gently mix all reagents by gentle inversion or swirling. Once an assay has been initiated, the wells should not be allowed to LIMITATIONS OF USE
The use of samples other than serum and EDTA plasma have not been Do not contaminate the Substrate Solution as this will render the whole validated in this test. There is no reuse protocol for this product. When making an interpretation of the test it is strongly advised to take all clinical data into consideration. Diagnosis should not be made solely on the findings of one Check the precision and accuracy of the laboratory equipment used during the procedure to ensure reproducible results. ASSAY PROCEDURE
The unused strips should be resealed in the foil bag, containing the desiccant, using the resealing zip-lock before being replaced at 2oC to Bring all the kit components and the test sample to room temperature (20°C to 25°C) prior to the start of the assy. One set of Standards should be run with each batch of test sample. CALCULATION OF RESULTS
Secure the desired number of coated wells in the holder. Record the position of the standards and the test samples on the EIA Data Calculate the mean absorbance value (A450) for each set of Standards, Unused strips should be resealed in the foil bag containing the Construct a point to point standard curve by plotting the mean desiccant, using the resealing zip-lock before being replaced at 2°C to absorbance obtained for each Standard against its concentration in ng/ml on graph paper, with absorbance values on the vertical or Y-axis 25μl of standards, test samples and controls into the and concentrations horizontal or the X-axis. Use the mean absorbance values for each specimen to determine the 100μl working solution of Progesterone-HRP Conjugate corresponding concentration of Progesterone in ng/ml from the 50μl of rabbit anti-Progesterone Reagent to each well.

Incubate at room temperature (20oC to 25 oC) for 90 minutes. If using a software package choose a polygon with data extrapolation At the end of the incubation period, discard the contents of the wells by flicking plate contents into a Biohazard container. Then strike the wells sharply against absorbent paper. Ensure adequate disinfectant EXPECTED VALUES AND SENSITIVITY

Flick plate contents into a Biohazard container. Then with the OD450 of the calibrators inversely proportional to their strike the wells sharply against absorbent paper. Wash the empty concentration. The OD of calibrator A should be greater than 1.5 and the OD of calibrator F less than 0.75 for the assay results to be valid. 10.
