Units:

mcg/mL FEU

Interpretation:

Less than 0.50 micrograms/mL: PE very unlikely.

.50 - 4.0 micrograms/mL: seen in ill patients and not diagnostic of thrombosis.

Greater than 4.0 micrograms/mL: suggestive but not diagnostic of DIC.

Critical Values:

None

Specimen Requirements:

3.2% sodium citrate tubes are acceptable provided they are filed to the line on the manufacturers label. Tubes must be full (see comments below). Whole blood specimens are stable for 4 hours at room temperature. Citrate plasma separated from cells is stable for 14 days at -20 degrees C.

Pediatric Specimen Requirements:

Add blood to the 1.3 mL mark of Pediatric BLUE top tube, 3.2 sodium citrate.

Reference Range:

Less than 0.500 ug/mL FEU.

Comments:

Draw volume is critical due to the liquid anticoagulant. Allow tubes to fill by vacuum. For tubes with rubber stopper, fill to line on label.

For tubes with plastic (Hemogard) cap, fill level is above top of label.

If drawing with syringe, do not remove vacutainer stopper, insert needle through stopper and allow tube to fill, by vacuum. Do not overfill vacutainer.

Note: Pediatric tubes have no vacuum; remove cap and add blood to the 1.3 mL mark. Do not overfill pediatric tube.

Moderately to marked hemolyzed or lipemic samples are not acceptable.

Units:

Critical Values:

500 ng/mL or greater.

Specimen Requirements:

3 mL blood in a LAVENDER top tube (EDTA); redraw if specimen clotted. Specimen is stable for up to 7 days refrigerated (2 to 8 C). If testing is delayed more than 7 days, store frozen at -20 C or less.

Pediatric Specimen Requirements:

0.5 mL blood in a LAVENDER top tube (EDTA); redraw if specimen clotted. Specimen is stable for up to 7 days refrigerated (2 to 8 C). If testing is delayed more than 7 days, store frozen at -20 C or less.

Reference Range:

100 to 250 ng/mL

Comments:

Test performed by immunoassay using Siemens Dimension EXL 200.

Samples for analysis of Cyclosporine should be collected 30 minutes to 1 hour prior to the next dose so that the measured concentration of drug represents trough level. The optimal therapeutic range for a given patient may differ from this suggested range based on the indication for therapy, treatment phase (initiation or maintenance), use in combination with other drugs, time of specimen collection relative to prior dose, type of transplanted organ, and/or the therapeutic approach of the transplant center.

Specimen Requirements:

12 mL urine in a sterile container.

Pediatric Specimen Requirements:

1 mL in urine sample cup

Reference Range:

Negative for nitrites and leukocyte esterase.

Comments:

The lab will perform a dipstick test and if the nitrites and/or the leukocyte esterase is positive, a urine culture will be ordered and resulted. If the dipstick is negative, no culture is ordered. Gram negative bacteria that most frequently cause urinary tract infections will reduce nitrates to nitrites, thereby giving a positive screen. Other significant infections should cause a positive leukocyte esterase due to the presence of WBCs.
