Specimen Requirements:

4 mL blood in a GREEN top, lithium heparin tube.

Do not collect into tubes that contain gel separator.

Pediatric Specimen Requirements:

Turnaround Time:

Test Schedule:

24 hours, 7 days a week.

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.

Turnaround Time:

Routine: 2 Hours

Test Schedule:

24 hours, 7 days a week.

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. If ordered, culture will be performed at Kaiser Regional Lab.

Turnaround Time:

Units:

Titer

Specimen Requirements:

0.5 mL CSF or 1 mL blood, RED top tube.

Pediatric Specimen Requirements:

 0.5 mL in a 4 mL RED top tube or 0.5 mL CSF

Comments:

This test is run on specimens positive for the cryptococcus screening test. A CSF titer of greater than 1:8 in patients with meningitis strongly suggests infection with Cryptococcus neoformans. Titers of 1:4 or less are presumptive and additional serologic follow up is strongly recommended. A negative test does not rule out Cryptococcal meningitis. A culture should be performed to confirm the diagnosis regardless of titer.

Comments:

A quantitative test will be performed at an extra charge on specimens that give a positive screening for Cryptococcus. Send required amount in addition to specimen sent for culture as remaining specimen is not suitable for culture after antigen test has been performed.
