ARPAN’S QUALITY POLICY
Arpan is committed to deliver
highest level of quality standard in its
products and services.
We believe that this can be
achieved only with continuous
improvements, global bench marking
& ceaseless effort to learn.
We aim to set new standards
for quality in our region & become a role
model for all those who want to contribute in
this sphere of public health.
PREFACE
Emerging from Arpan’s vision, this document is a very specific effort towards bringing
entire chain of professionals working in blood transfusion cycle to a common
understanding of the complex process.
Starting with the point in the hospital where it is decided to opt for blood transfusion to
the logical conclusion of patients acceptance of this emergency drug, every step is
discussed with detailed medical understanding as well as administrative check points.
The purpose is to ensure that there is no error whatsoever at any point in this
lifesaving mechanism.
We are sure, clinicians, paramedical staff, blood banking staff and administrative
professional touching this process would find this document very useful and pragmatic
for their day to day work and will make entire cycle error free and thus safest.
We would be more than happy to receive your feedback / suggestions on this on

BLOOD REQUEST
REQUISITION FORM FILLING
1
Patient information
1.
Always write patient’s full name as multiple requests
come to blood bank from many hospitals & there are
chances of two requests of same name & surname
from two different hospitals.
2.
Compulsory write patient’s blood group on form. If
any discrepancy is noted in blood group written on
requisition form and blood group detected in blood
bank on patient’s sample, it can be resolved & right
blood can be issued to the patient.
Product requirement
1.
Always write date & time of requirement of blood /
component unit, so that unit can be reserved, if it is
going to be available meanwhile.
Hospital information
1.
Always write treating doctor’s name & mobile no. on
requisition form, so that in case of any problem or
doubt, it can be resolved by talking with him.
2.
Always give hospital seal on requisition form. It is
legally compulsory & possible malpractices can be
avoided.

NAT TEST
•
NAT testing lab is established at Arpan Blood Bank, Nashik. It is 2nd Stand alone blood bank in the country to start NAT
testing facility. NAT tested blood will be available at all centres of Arpan blood bank across State.
•
NAT – Nucleic Acid Amplification test used to detect HIV, HBV & HCV infection.
•
It is most advanced technology used Worldwide.
•
In this test, viral RNA is captured, amplified & detected.
•
As it detects genetic material, detection is accurate & very early than conventional methods (ELISA & Cheminileuscence).
window period reduction
Infection

technology using best 4th generation kits)

5.6 days
HBV
53.3 days
24.6 days
HCV

Pilot Study –
•
The first Indian study for NAT testing shows that 1 in 1,528 blood units are found to be positive for any of the Three viruses which
were seronegative by ELISA technology.
•
A pilot study at AIIMS among 5,818 donors shows that 1 in 1,164 blood units were found to be positive for any of the three viruses
which were seronegative by ELISA technology.
There is no reported case of either of three infections after transfusion of NAT tested blood.
Cost-
As NAT test is done in addition to routine ELISA test, extra cost is added for NAT tested unit. But the cost is negligible
considering the physical, mental trauma & economic loss for treatment of these diseases.

-It is like unnecessary multidrug therapy.




-Recipient is exposed to single donor.
-Leucoreduced platelets are obtained so risk
of transfusion reaction and platelet
refractoriness is reduced.
-Recipient is exposed to many donors.
-Risk of alloimmunization and so platelet
refractoriness
-Chances of transfusion reaction are more as
leucoreduction is not always possible.

Reasons

- Fresh Frozen Plasma can be given when all
clotting factors are required.
- It also supplies Albumin.
- If we want to supply factor VIII (AHF), VWF or
Factor XIII, Cryoprecipitate should be preferred
over FFP as volume is reduced & so chances
of transfusion reactions.

As per individual



2. Fresh Blood
Only increase in
HB% as per
Whole Blood
Fresh blood is not an option because blood
needs to be preserved at 2-60C, till testing is
done and 80-90% platelets become non viable
at 2-60C. Hence this blood will not supply viable
platelets. You will only get RBCs & Plasma from
Fresh Blood.
1. PCV + FFP
/CRYO
As per individual
PCV & FFP or
CRYO


2. Fresh Blood
Only increase in
HB% as per
Whole Blood
Fresh Blood is not an option because all labile
clotting factors get destroyed at 2-60C within 6
hrs. And it usually takes more than 6 hrs from
collection to issue. Hence fresh blood will not
supply clotting factors.
2. Cryoprecipitate
(CRYO)
6
PLASMA BY APHERESIS (PL-A)
• In western India, Arpan blood bank, Nashik is the only blood bank to have Plasma
Apheresis facility.
• As platelets are collected by apheresis, 500ml plasma can also be collected by
apheresis. The unit of 500 ml plasma collected by apheresis is called PL-A.
• Advantages of plasma by Apheresis (PL-A).
1.
As plasma is collected & frozen within 2 hours, the quality of product is much
superior & the yield of clotting factors is much high than routine FFP.
2.
The desired effect of 4 FFP unit is achieved by single unit of PL-A. So the risk
of exposure to four different donors & therefore TTI is significantly reduced.
3.
The same donor can donate another unit of PL-A after 15 days.

2. Rh blood grouping system
• ABO antibodies are naturally occurring i.e. opposite antibody (to antigen on RBCs)
appears in plasma naturally within few months after birth.
• In contrast Rh antibodies are not naturally occurring. They are immune antibodies.
They develop against antigenic stimulus i.e. when Rh positive RBCs enter in
circulation of Rh negative person.

If Major crossmatch is incompatible, then donor cells (which are less in volume) will react with
antibodies in patient’s plasma (which is large in volume) & will get destructed completely to cause
serious hemolytic reaction. So it is called Major.
•
If Minor crossmatch is incompatible, then donor’s plasma (which is less in volume) will get diluted in
patient’s plasma (which is large in volume) and there are less chances of reaction between
antibodies in donor’s plasma with antigens on patients cells & so least chance of hemolytic reaction.
So it is called Minor.

PLATELET COMPATIBILITY
• ABO antigens are not usually expressed on platelets. They are expressed
on platelets in only 7% population, in which they are expressed weakly and
on some platelets.
• So platelet cross matching is not applicable for platelet transfusion.
Platelet can be transfused across group safely i.e. any group platelets can
be given to any group patients.

Rh COMPATIBILITY
•
‘Rh positive’ patient can receive ‘Rh positive’ as well as ‘Rh negative’
blood or blood components.
•
'Rh negative' person should receive ‘Rh negative’ whole blood and
PCV.
•
For plasma & platelet transfusion, when ‘Rh negative’ units are not
available, ‘Rh positive’ units can be transfused weighing the need of
transfusion and risk of Rh alloimmunisation. While transfusing ‘Rh
positive’ unit to ‘Rh negative’ woman with child bearing potential, Rh Ig
prophylaxis should be given.
•
For cryoprecipitate transfusion Rh compatibility is not applicable.
29
COMPATIBILITY & SELECTION OF UNIT FOR NEONATAL TRANSFUSION
Neonate: Patient under the age of 4 months are neonates for blood transfusion purpose.
Blood Request: Write compulsory ‘whether you suspect HDN or not’ on requisition form .
Blood Samples: Send blood samples of both –
1. Baby
2. Mother
Compatibility Testing:
1. First direct coomb’s test (DCT) on baby’s RBCs & indirect commb’s test (ICT) on maternal
plasma are performed to r/o HDN.

Rh compatibility if e/o HDN:
If there is e/o HDN, unit should be Rh compatible to both baby’s & mother’s group i.e. if either
of two is Rh negative, then select Rh negative unit.
General rules of neonatal transfusion:
1.
Don’t use PCV with SAGM solution (additive solution) for neonatal transfusion, as it contains
mannitol. Neonatal transfusion is the only contraindication for using PCV with SAGM solution.
2.
If you are transfusing blood of optional group (whether there is e/o HDN or not), use semi-PCV
(i.e. whole blood from which plasma is removed partially) with low anti-A or anti-B titre.
3.
Use fresh blood (<48hrs old preferably) for neonatal transfusion. It should not be more than 5
days old to avoid risk of hyperkalemia.
4.
For plasma & platelet transfusion, same group unit as that of baby, should be used. If there is
e/o HDN & mother is Rh negative, use unit of Rh negative group.

FFP, RDPC, SDPC, & Cryoprecipitate.
Change BT set every 12 hrs., if patient is requiring ongoing transfusion.
• Warming –
Warming of blood unit is not needed. Infusion of 2-4 units of
refrigerated blood over several hours causes no harm.
Warming is needed in following conditions –
• Infants receiving exchange transfusion.
• Patients receiving rapid transfusion through central venous line.
• Patients receiving rapid & massive transfusions.
• Patients with cold – antibodies.
(If warming is needed, unit should not be warmed above 370 c.
Excessive warming may cause hemolysis in unit & can lead to serious
transfusion reaction).
• Don’t add any medication to unit. You can add only normal saline or 5% albumin to dilute.
37
TIME LIMITS FOR TRANSFUSION
• WB / PCV – Within 3-4 hours.
• FFP
– Within 15-20 mins.
• Cryo
– Within 5-10 mins.
• Platelets
– Within 15-20 mins.
(RDPC & SDPCs)
( If room temp. is 22-250c.
At higher room temp., there should be
shorter out of refrigerator time).

THEIR MANAGEMENT
39
INFECTIOUS ADVERSE TRANSFUSION REACTIONS
Reaction
Presentation
Transfusion transmitted
infections
HIV, HBV, HCV, Malarial
parasite, T.pallidum (causative
agent of syphilis) are the
organisms which can get
transmitted through transfusion.
Presentation will be as per
infection transmitted.
Transfusion associated
sepsis
Fever, chills hypotension, septic
shock, DIC
Cause
1. During window
period, HIV, HBV &
HCV infections can
not be detected. The
test results in blood
bank are negative.
2. Technical &
interpretational errors
Bacterial
contamination due to
technical errors
How to avoid
- Risk of transmission of HIV, HBV &
HCV through transfusion can be
reduced to nearly zero %, by using
NAT tested blood.
- By using advanced fully automated
systems for testing, technical &
interpretational errors can be
minimized.
- Take aseptic precautions during
blood collection, product
preparation & at the time of
transfusion.

Cause
How to avoid
Allergic reactions
(Very common)
Urticaria, pruritis,
flushing, rashes
Antibody to donor
plasma proteins
- Use PCV instead of WB
- Use cryoprecipitate instead of
FFP, when indicated
Non hemolytic febrile
transfusion reactions
(NHFTR)
(Very common)
Fever,
chills/rigors,
headache,
vomiting
Leukocytes
- Accumulated
cytokines
- Antibody to donor
leukocytes
- Use leuco-depleted components
Anaphylaxis
Urticaria,
hypotension, bronchospasm,
respiratory distress,
local edema

plasma proteins
- Accumulated
cytokines
- Use leuco-depleted components
Transfusion associated
acute lung injury
(TRALI)
Respiratory failure,
hypotension, fever,
bilateral pulmonary edema,
hypoxemia
- Antibodies to
donor leukocytes
- Use leuco depleted components
Platelet refractoriness
No rise in platelet count on
platelet therapy
- Leukocytes
- Allomunisation,
HLA antigens
- Use leuco depleted components
