Send by overnight express mail. Negative HOMOCYSTEINE 342 CH 83090 15 uL plasma from either an EDTA (purple) tube or heparinized (green) tube or serum Please note: Serum may be sent, but plasma is the sample of choice. 2 - 4 Days Heparinized and EDTA plasma are the samples of choice, but serum is also suitable for use. It is important to separate the plasma or serum from the cells as soon as possible after collection, as synthesis of HCY will take place in red blood cells after sampling. Samples should be stored on ice between the time of draw and centrifugation. Note that storage on ice makes the use of serum samples particularly difficult. Centrifuging serum samples before a complete clot forms may result in the presence of fibrin. To prevent erroneous results due to the presence of fibrin, ensure that complete clot formation has taken place prior to centrifugation of samples. Some samples, particularly those from patients receiving anticoagulant therapy, may require increased clotting time. 5.0 - 12 umol/L HUMAN CHORIONIC GONADOTROPIN (HCG), QUANTITATIVE 305 CH 84702 1 mL serum, ambient, refrigerated or frozen 1 - 3 Days Must be frozen within 24 hrs of draw to remain viable. <5. mIU/mL IgA, IMMUNOGLOBULIN A 44 NEPH 82784 1 mL serum, ambient, refrigerated or frozen 1 - 3 Days   82 - 453 mg/dL IGE, IMMUNOGLOBULIN E 751 CH 82785 1 mL serum, ambient, refrigerated or frozen 1 - 3 Days   <100 IU/mL IgG, IMMUNOGLOBULIN G 43 NEPH 82784 1 mL serum, ambient, refrigerated or frozen 1 - 3 Days   751 - 1500 mg/dL IgM, IMMUNOGLOBULIN M 45 NEPH 82784 1 mL serum, ambient, refrigerated or frozen 1 - 3 Days   46 - 304 mg/dL IMMUNOFIXATION ELECTROPHORESIS (IFE) 115 EL 86334 1 mL serum, ambient, refrigerated or frozen 2 - 4 Days   Normal KU 279 IPP 86235 1 mL serum, ambient, refrigerated or frozen.
