What is IG?Previous Instrument
• Only counted mature Myeloid cells
• Flags if immature cells present
• Reflex to manual count (100 cells)
**New Instrument**
• Identifies & Quantifies ImmatureMyeloid cells
Immature Granulocyte (IG) Promyelocytes Myelocytes Metamyelocytes
• Counts 32,000 cells Flags if atypical cells present (WAM) And reflexes to manual review
(Cellavision)
Neutrophil count Bands Neutrophils
*Rapid, Accurate, Precise*
How does IG compare to Band Count?
• Band Count is poorly reproducible
• Criteria for Bands is subjective
– Three different definitions
– “How pinched is the nucleus?”
If TRUTH = 10 Bands per 100 WBC (10% Bands)100 cell count 5% to 16% Bands
1,000 cell count 8% to 12% Bands
The manual band count is impreciseNeutrophil?

• ITR has been used as an index to predict neonatal sepsis– Thought to be relatively stable, with results
independent of birth weight and gestational age
– Controversial
• Generally accepted reference range < 0.2
• Another study 0.05 – 0.27
• ITR calculation relies on Band Count– Cannot be precise
• IG in neonatal population– Needs more study
– Needs Physician buy in
How does IG compare to ITR?
Variable by postnatal age
(normal ranges)
ITR Age
< 0.16 0‐24 hours
< 0.13 60 to 120 hours
< 0.12 5‐28 days
Postnatal age of 4 hours
Healthy babies
ITR Age
0.05 – 0.27 4 hours
ITR = I:T Ratio = Immature neutrophils (bands, metamyelocytes, myelocytes, and promyelocytes) to Total Ratio (Manual Differential)

Patient BAdmit Dx: Fever
D/C Dx: Salmonella 17 ‐ 27 0.33 ‐ 0.67 2.8%
• The band count is not sensitive enough to predict sepsis,• Pediatric Literature: Ratio of ITR of < 0.2 has a high negative predictive value
Cut offs
Band count >10 (One possible criteria for SIRS)IT Ratio <0.2 has high negative predictive value IG: >1% indicates a left shift>3% may predict positive blood cultures

What does IG mean in my patient?
IG% and IG# – Early screen for sepsis
• Better indicator for infection than WBC
• Comparable to ANC
• IG% >1% indicates a left shift
• IG% >3% may predict positive blood cultures with:
• 98% specificity
• 92% PPV
– Detect myeloproliferative disorders
Neutrophil count includes bandsAutomated Neutrophil Count= Manual Absolute Neutrophil Count= ANC

Published IG Studies
In‐House IG Studies
IG to help determine infection/sepsis1. Chart review of patients with Sepsis Alerts
• Patients with sepsis (True Positives)
• Patients without sepsis (True Negatives)
• Compare IG% to determine cut off values
2. Patients with positive blood cultures
• IG and ANC as an indicator for infection/sepsis (SIRS Criteria)
3. What to expect in various disease states, does IG indicate chorioamnionitis?
4. IG versus ITR in pediatric patients.
5. Does IG/ANC/Bands correlate to Procalcitonin?

IG in Care Pathways• LAB:
– Continue to make results easier to understand– Currently report IG with auto dif– We will be adding automated IG to manual dif– Note: Neut# = ANC How to make more understandable?– Determine important cut‐offs– Interpretative messages
• Hospital– SIRS criteria
Where’s IG?
IG only reported with Auto Dif
Neut# = ANCNeut# automatedBetter than manual
Where’s IG%?
SIRS (Systemic Inflammatory Response Syndrome)International Sepsis Definition Conference (ISDC) in 2001
Definition of SepsisWhen an adult patient with an infection looks “sick,” “septic” or “toxic” and has any two or more of the following criteria:
• Fever ≥101°F or hypothermia (<96.8°F) • Heart rate >90 beats/minute • Respiration rate >20 breaths/minute • White blood count >12,000 µL or <4,000 μL or with >10% bands
Coding: CMS recognizes any two or more of the above criteria as indicative of sepsis

Immature Platelet Fraction (IPF)
Questions to consider
?What is IPF
?What does the IPF result mean to my patient
? Published IPF studies
? In‐House IPF studies
?Where should IPF be added to Care Pathways
What is IPF?Previous Instrument

– Ave size of plts
• IPF (Immature Plt Fraction)
– % Immature plt/total plt
**New Instrument**
*Rapid, Accurate, Precise*
11/2/2012
17
What does IPF mean to my Patient?
↓ Plts + IPF = Production disorder
↓ Plts + IPF = Destruction mechanism or BM Recovery
• Evaluate mechanism causing thrombocytopenia
• IPF recovers ~3 days earlier than platelet count
• Predict platelet count recovery
• Determine need for platelet transfusion
Published IPF Studies
11/2/2012
18
In‐House IPF Studies
• Usefulness of IPF as a differential diagnosis of ITP/TTP
• IPF in transfusion practices• Determine if IPF impacts prophylactic platelet transfusions
• Determine how to include IPF in transfusion protocol
• IPF as an aid to avoid unnecessary bone marrow biopsies
• IPF to determine bone marrow recovery and avoid ordering of HLA typed products
IPF in Care Pathways
• LAB:– What PLT result to trigger reflex IPF testing?
• Started with 30,000• Changed to 50,000
– How to order IPF?• Orderable: Platelet count with IPF• Stand alone platelet count order will reflex to IPF
• Hospital– Evaluation of thrombocytopenia– Assess need for transfusion– Assess bone marrow recovery

• Same test as Reticulocyte Hemoglobin Content (CHr)
• Qualitativemeasure of Hb in reticulocytes.
• Cellular evaluation of iron status• Help diagnose iron deficiency
• Not affected by uremia or inflammation
• Faster response to treatment than routine iron tests• Monitor response to treatment more closely (3 days)
• Improve EPO usage by identifying non‐responders earlier
11/2/2012
21
Published RET-He Studies
In‐House RET-He Studies
• Economic value of screening for iron deficiency in children
• RBC Transfusion protocol – determine how to add RETIC‐Comprehensive (RET‐He)
• Economic value of screening for ID and IDA, medically treating prior to surgery and avoiding PRBC transfusion– Pre‐Op Anemia elective Ortho surgery
– Pre‐Op anemia screening in Cardiac valve cases
• Hospital patients: Evaluate RET‐He in EPO/Iron treatment– Identify Non‐Responders faster
– Adjust iron or EPO dosage
11/2/2012
22
RET-He in Care Pathways

IG %Immature granulocytes (promyelocytes, myelocytes, metamyelocytes) > 1.0% indicates that a left shift is present. BANDS are included in the automated neutrophil count and not in the immature granulocyte count.
IPF %Low PLT + low IPF suggests a bone marrow production disorder.
Low PLT + high IPF suggests peripheral destruction (e.g. ITP, TTP, HIT, DIC, autoimmune) or bone marrow recovery. Trending of serial IPF measurements is recommended when evaluating for bone marrow response.
RET-HeAdults: The RET‐He threshold for defining iron deficiency in adults is < 29 pg. (KDOQI Guideline Changes).
Pediatrics: Less than 27.5 pg is indicative of iron deficiency.
IPFValues above normal range indicates an increase in RBC cellular response from bone marrow.

Greater collaboration with other clinicians • Pathologist/Lab leadership
• Collaboration with other physicians and ACO leaders
• Rectify lack of understanding:– Analytic role and expertise of pathologists not appreciated
– Pathologists know most effective applications of laboratory medicine
• Pathologists/Lab easily overlooked during the development of ACOs
• Pathologists/Lab should proactively assert their ability to help the ACO meet its goals
Connect with the Big Picture
How to pay for pathologist contributions?• Traditional fee‐for‐service model not appropriate • Adoption of guidelines may decrease the volume of laboratory tests
• And decrease income derived from fee‐for‐service payments
• Pathologists/Lab add value• Not to specific patients• To the development of systems and guidelines that globally reduce costs and potentially improve patient care
