PARASITE EXAM*

MERCY LAB CODE

PARSIT

Specimen:

Stool delivered within 2 hour of collection: 5 – 10 gm of feces submitted in clean container with tight fitting lid.  If specimen will not be delivered within 2 hour of collection:
It is recommended that stool specimens be collected and submitted on three consecutive days, due to the intermittent nature of some parasites.  

Specimens received in SAF fixative will be sent to SHL, Iowa City for testing (order MISM). Take specimen to Microbiology dept.

Comments:

• Test will NOT detect Cryptosporidium.  See “Cryptosporidium” if this test is desired.
• This test is useful for patients who have traveled to foreign countries, or an area of the USA where helminth (worm) infections have been reported with some frequency.
• For patients who have not traveled, order Giardia and Cryptosporidium Antigen testing (GLCP) instead of Parasitic Exam, performed at Mercy Lab.
• Urine may also be submitted, if Schistosomiasis is suspected. Order as a CMIS in the LIS and order test code-OAP on the Mayo PC. Urine must be tested within 48 hours of collection.  Submit 10 ml from a random urine collection, preferably collected between the hours of 12 noon and 3 pm.  Do not use preservatives.  Send refrigerated in a sterile, screw-capped container.

Mercy Inpatient Comments:

• Specimens collected from inpatients after the fourth hospital day will not be tested without prior approval from the Microbiology Department

RL Client Comments:

• Mark OVA & PARASITES (under Direct Stool Tests) on order form.
• Submit stool specimen within 2 hours of collection. If specimen will not be delivered within 2 hours of collection, follow instructions below for using the EcoFix transporters:
       *Transfer enough stool specimen to bring the liquid level up to the fill line
         indicated on the ECOFIX preservative vial.  DO NOT OVERFILL.
       *Mix thoroughly.  Pieces should be pea size or less.
       *All formed specimens must be broken up in the preservative. 
             *Specimens in preservative must be tested within 5 days collection

Cause for rejection:

Specimens collected within 7 days of a barium or bismuth enema are not suitable for examination.  Specimens should not be contaminated with toilet water or urine (when collecting feces).

Processing:

Ambient transport (refrigerated ok).  Mayo order code- OAP

Reference value:

Negative
If positive, organism will be identified.

Draw one waste tube (blue top tube or plain red top tube.) followed by 2 blue top Vacuette Greiner tubes.  Blue top Greiner tubes fill only half full.  Alternately, draw 2 full BD blue top tubes.  Use 21 gauge or larger needle to draw.  If drawing with a syringe, use first syringe to draw waste or other tests, change syringe and use 2^nd syringe for this test.  GENTLY invert tube 5 times to mix. DO NOT shake or send in pneumatic tube system.  DO NOT refrigerate or centrifuge. Always draw blue top tubes before purple top tubes.  Flag top of tubes for indication not to spin.

Results are reported in ARU (Aspirin Reaction Units).
 >550  ARU - Platelet dysfunction consistent with aspirin has not been detected.                                         
<550 ARU  - Platelet dysfunction consistent with aspirin has been detected.

This assay is not for use in patients with underlying congenital platelet abnormalities, patients with non-aspirin induced acquired platelet abnormalities or in patients receiving non-aspirin anti-platelet agents. 
(May be used in patients treated with selective COX-2 inhibitors, e.g. celecoxib (Celebrex).

Verfiy Now Aspirin Assay is a qualitative assay to aid in the detection of platelet dysfunction due to aspirin ingestion.  Other uses of the ARU value is not endorsed by Accumetrics and is not FDA cleared.

Interference Studies:

The following medications may cause a change in platelet function.

Patients who have been treated with epitifibatide (Integrillin) and tirofiban (Aggrastat) should not be tested for 48 hours, or abxicimab (ReoPro) for 14 days.

Anti-Platelet agents can inhibit platelet function and may result in a decreased ARU value independent of the effects of aspirin.  Average duration times are:  Plavix and Ticlid - 5 days, Aggrenox - 10 days, Persantine and Pletall/Cilostazol - 12 hours.

NSAID's inhibit platelet function, but not irreversibly like aspirin.  Average times for inhibitory effects for each drug are:  Ibuprofen - 8 hours: Naproxen, Diclofenac, Indocin - 24 hours, Feldene 50 hours.

GENTLY invert tube 5 times to mix.  DO NOT shake or send in pneumatic tube system. DO NOT refrigerate or centrifuge.  Always draw blue top tubes before purple top tubes.  Flag top of tubes for indication not to spin.

Therapeutic range is <230 PRU for person taking thienopryridine drug.

Normal range:  PLT Inhibition P2Y12: 194-418 PRU (P2Y12 Reaction Units) for person not taking thienopryridines drugs.

Patients with inherited platelet disorders such as vonWillebrand Factor Deficiency, Glanzmann Thrombasthenia and Bernard-Soulier syndrome have not been studied with this assay.  Therefore this assay is not intended for use with these types of platelet disorders.

Interfering Substances:

1. Glycoprotein IIb/IIIa inhibitor (abciximab, eptifabtide, and tirofiban) and antiplatelet agents (cilastazol) inhibit platelet function.  Some degree of platelet inhibition by these drugs was detected.
2. Drugs that affect platelet function may be detected up to 14 days after ingestion.
3. Other classes of commonly used drugs were tested with no significant effect on assay performance: antioxidants, ACE inhibitor, antiarrhythmics, anticoagulants, aspirin, antidepressants, insulin, allopurinol, alcohol, beta blockers, bronchodilators, calcium channel blockers, gastrointestinal medications, betamethasone, lovastatin, NSAIDs (including COX-1 and COX-2 enzyme inhibitors), and the thyroid hormone L-thyroxine. 
   The thrombolytic agent streptokinase showed no significant inhibition of platelet function.
4. Results may not be available for patients with a platelet count <50,000.

A Platelet Count must also be ordered if one has not been performed at Mercy Medical Center-North Iowa within one week prior to platelet infusion.  Pheresis platelets and Acrodose platelets are stocked depending upon our blood supplier's availability.  Both are prestorage leukoreduced and equivalent in dosage to 6-8 random platelets.  An order for pheresis platelets may be filled with either product. If irradiation is need, indicate so in the comment field for EACH order placed.  It is not sufficient to send a message to cover all orders.  Call the Lab when irradiated platelets are ordered.  Orders for irradiated platelets must be entered into the computer and called to the Lab no later than 1515, Monday through Friday.  Special arrangements must be made if irradiated products are requested after 1515 or on weekends or holidays.

PHERESIS PLATELETS:
Order PLATELETS FOR INFUSION (TPLT)
Units ordered: The default is 1 unit.  Any additional instructions, such as IRRAD (irradiation needed), can be entered also at this time. All pheresis platelets are leuko depleted and therefore a leukocyte (WBC) removal filter is not needed.
