Biobank material
A unique collection enables high-quality research. The Blood Service Biobank collects samples and data as part of blood donation from blood donors who have joined the Biobank.
Why choose us?
The Blood Service’s quality assurance system and our highly competent staff help ensure that our samples are of high quality. It is our aim to constantly improve our services.
Our samples are collected from people eligible to donate blood from all over Finland, and our collection is constantly growing. Our material includes longitudinal samples, special collections and genomic data.
Depending on the needs of your research project, we can carry out tailored sample collections or deliver material based on factors such as phenotype or genotype. We can deliver samples fresh or frozen. You can apply for material for research purposes based on desired criteria, such as specific health or demographic data. Our material is also well suited for use as reference material.
Off-the-shelf samples
From our sample collection we can select samples based, for example, on donor phenotype or genotype as appropriate. Time stamps for collection, processing and freezing are available for all samples. The samples are collected during blood donation from people who meet our blood donation criteria and have joined the Biobank.
Cord blood collection
Between 1999 and 2013, the Finnish Red Cross Blood Service collected cord blood for its Cord Blood Bank from consenting mothers who had just given birth. These samples were transferred to the Blood Service Biobank in 2023 after specific consent was obtained.
The cord blood products contain blood collected from the placenta following childbirth. During production, samples were taken from the cord blood units for possible further testing. Blood samples (plasma, serum and leukocytes) from the mother were also stored in the archives for possible further testing.
The samples meet all assay criteria for clinical products. The samples are stored in a liquid nitrogen freezer at -180°C.
Stem cell products from cord blood
197 donors.
Blood product sample types: Plasma (native), Plasma (20% HES), Live cells (10% DMSO), DNA.
Archive sample types (maternal samples): Plasma, Serum, Buffy Coat.
Data associated with the samples
Time stamp for cord blood product processing, blood group, cell counts, tissue type (including HLA A, B, C, DRB1), pregnancy medical records and small blood count.
Sample collection based on research project needs
We’re able to carry out tailored sample collections based on factors such as genotype or phenotype. We can also carry out sample collections in a certain area of Finland, within a certain age group or based on other desired criteria. We’re able to provide whole blood samples or blood parts, including fresh or frozen whole blood and buffy coat. We only collect samples from blood donors who have joined the Biobank.
Whole blood samples
Samples are collected as part of blood donation from people who meet our blood donation criteria. The samples are primarily collected into 4–10 ml EDTA tubes, but if necessary, can also be collected in other types of sampling tube (e.g. Lithium-Heparin, Cell-Free DNA BCT). The total sample volume from each person is max. 12 ml. The samples can be delivered fresh or frozen.
Buffy Coat
Samples are collected as part of blood donation from people who meet our blood donation criteria. The buffy coat is the leukocyte-thrombocyte fraction of centrifuged donated blood and also contains a small amount of plasma and erythrocytes. The samples are delivered the day after blood donation. The total volume of each Buffy Coat is 40–50 ml (40–50 g).

Data available
The data available from our data sets includes information on donors and data from sample analyses. Donor information includes age, sex and place of residence. More specific data, such as genotype or immunogenetic data*, is available for some donors. Information concerning donors’ blood donation history, including blood group, haemoglobin, number of donations and eligibility for donation, is also available. Laboratory data from sample analysis is also available for researchers (see * below), and special analysis data returned to the Biobank by research projects is available for use in subsequent studies. The numbers are approximates, updated 03/2024.
| Data | Data available / donor | Additional information |
