Question from Hind Al-Otaibi (firstname.lastname@example.org)
Subject: Query about WBC labelling Plasma Expander
Date: Tue, 30 Oct 2012 11:27:40 +0300
Dear Dr. Sobal,
I would like to ask about the plasma expander used in the white blood cells labeling . In our lab we are using 6% Hetastarch(Hydroxyethyl starch ( HES 130/ 0.4) )IN ISOTONIC SODIUM CHLORIDE solution .
Ingredients in detail are:
Poly( o-2-hydroxyethyl) starch 60.00 g
Molar substitution 0.38 – 0.45
Mean molecular weight = 130,000
Sodium chloride 9.00 g
Electrolytes Na+ 154 mmol/l Cl– 154 mmol/l
Theoretical osmolarity 308 mosm/l
Titratableacidity < 1.0 mmol NaOH/l
PH: 4.0 – 5.5
I would appreciate it if you see the above ingredients and tell me is it the right concentration to be used for erythrocyte sedimentation in the white blood cells labeling procedure.
Many thanks and kindest regards

Answer from Napoleone Prandini:
In my opinion the best product to obtain a fast sedimentation of RBC for leukocytes labelling is the HAES Steril 10%: you can find all the informations about the chemical composition and clnical effects on WEB page:
1 litre contains:
|–||Medicinal active ingredients:
Poly (0-2-hydroxyethyl) starch 100.00 g,
Degree of substitution 0.40-0.55,
Average moleculare weight Mw: 200.000,
|–||Active ingredients: Sodium chloride 9.00 g,
Na+: 154 mmol/L, Cl– : 154 mmol/L
|–||Other ingredients: Sodium hydroxide, Hydrochloric acid, water,
Titration acidity: < 1 mmol NaOH/L,
Theoretical osmolarity: 308 mosm/L,
pH value: 3.5-6.0

Dr. Funda AYDIN has successfully completed the course on “CERTIFICATE PROGRAM ON RADIOLABELING OF BLOOD ELEMENTS” organized by ISORBE, andNuclear Medicine Department of the Akdeniz University, Antalya, Turkey on 27-29 March 2011 and fulfilled all the requirements defined by the ISORBEnecessaryto take responsibility for the radiolabeling of bloodcells.
Here are the copies of her certificate and some words from the ISORBE educational committee:
– After completion of the Certificate Course in AntalyaTurkey, 27-29 March 2011 Dr. Funda Aydin has reported her results. Enclosed please find labeling of 15 WBC’s and 5 WBC images and the required forms which meet our requirements for Certification.
I propose to award her with an ISORBE Certificate.

- – Excellent the labelling efficiency & images- Funda really did a good job. Of course she deserves the ISORBE certificate. Congratualtions KUTLAN & FIRAT. Dra Victoria E. Soroa
– Excellent! I agree. Dr. Helmut Sinzinger
– Excellent work. Congratulation to Funda and Firat. Evaluation passed. Dr. J. Martin Comin
Ms. Leena DEEB has been awarded with an ISORBE Certificate based on her completion of CERTIFICATE PROGRAM ON RADIOLABELING OF BLOOD ELEMENTS in Antalya, Turkey on 27-29 March 2011 and meeting all the requirements defined by the ISORBE necessary to take responsibility for the radiolabeling of blood cells.
Here are the copies of her certificate and some words from the ISORBE educational committee describing her performance:
· Ms. Leena Deeb has been working on radiolabeled blood cells for several years in Kuwait. She has worked very hard to introduce proper conditions for blood cell radiolabeling and finally reported excellent results. I propose to award her with an ISORBE Certificate.
