AI-assisted haematology analysis has the potential to completely change how blood illnesses are identified and treated. Large amounts of data may be swiftly and correctly analysed by AI algorithms, which can aid in the early detection of blood problems, result prediction, and selection of the most effective treatments.

The study of blood smears is one example of how AI is utilised in haematology. Hematologists typically use a microscope to detect and count the various blood cells present in blood smears. Machine learning algorithms can quickly and accurately identify various blood cell types and abnormalities, such as sickle cell anaemia or malaria, using digitised images of blood smears. This can enhance patient outcomes and aid in the early diagnosis of blood diseases.

The analysis of genetic data is another way that AI is used in haematology. AI algorithms can find genetic changes that might be causing the disease by examining the genetic makeup of people with blood issues. AI algorithms can detect genetic alterations that may be influencing the development of blood illnesses by examining the genetic composition of patients who have them. This can assist in creating individualised treatment regimens that focus on the disorder’s underlying genetic cause.

A common blood test called a CBC (Complete Blood Count) is used for evaluating a person’s general health and screen for a number of diseases, including blood cancer. Red blood cells, white blood cells, and platelets are just a few of the different blood cell kinds and numbers that are identified by the CBC.

However, because CBC only offers a broad overview of the blood cells in the body and because blood cancer may not always result in appreciable changes in CBC results, it may not be sufficient to identify blood cancer. A diagnosis of some blood cancers, such as early-stage leukaemia or lymphoma, may not be confirmed by CBC alone and may necessitate additional diagnostic procedures.

Among other diagnostic procedures, bone marrow biopsy, flow cytometry, and genetic testing may be used to find blood cancer. These tests can assist in making a more precise diagnosis of the kind and stage of blood cancer, which is necessary for choosing the best course of action.

In conclusion, while CBC is a valuable blood cancer screening tool, it might not be sufficient to provide a conclusive diagnosis, and further testing might be necessary to confirm a suspected diagnosis.

Machine Learning


Tumours that affect the blood, bone marrow, and lymphatic system are referred to as haematological malignancies. Examples of these tumours include leukemia, lymphoma, and myeloma. By examining huge datasets of patient data, test findings, and medical imaging, machine learning (ML) algorithms can help with the detection and diagnosis of these malignancies. Here are some typical methods for utilising ML to find haematological malignancies:

  1. Image analysis: Machine learning algorithms can be taught to examine medical images like CT scans, MRIs, and PET scans to find patterns and abnormal cell proliferation that might point to haematological cancers. The type and stage of cancer can also be determined with the help of these algorithms.
  2. Biomarker analysis: Biomarkers are observable signs of a biological condition, such as the presence of particular proteins or genetic abnormalities. Large datasets of biomarker data can be analysed by machine learning algorithms to find trends that might point to haematological malignancies.
  3. Electronic health record (EHR) analysis: Electronic health records contain a wealth of information about patient medical history, lab results, and diagnostic imaging studies. It is possible to train machine learning algorithms to examine EHR data to find trends and risk variables that could be connected to haematological malignancies.
  4. Blood analysis: Blood samples can be analysed using machine learning algorithms to find aberrant cell populations or gene alterations that could be signs of haematological malignancies.


For some types of blood cancer, such as chronic lymphocytic leukemia (CLL) and low-grade lymphoma, recurrence may occur years or even decades after initial treatment, while for other types, such as acute lymphoblastic leukemia (ALL) and aggressive lymphoma, recurrence may occur within months of treatment.

  1. Risk assessment: Machine learning algorithms can be trained to analyze patient medical records and identify risk factors that may increase the likelihood of developing a hematological condition or disease. This information can be used to develop personalized prevention and treatment plans.
  2. Disease detection: Machine learning algorithms can be trained to analyze medical images, such as blood smears or bone marrow biopsies, to identify abnormal cell growth patterns that may be indicative of a hematological condition or disease. This information can be used to facilitate early detection and intervention.
  3. Treatment response prediction: Machine learning algorithms can be used to analyze patient data and predict the likelihood of treatment success or failure based on factors such as disease stage, age, comorbidities, and genetic makeup. This information can be used to personalize treatment plans and improve patient outcomes.
  4. Disease progression prediction: Machine learning algorithms can be trained to analyze patient data and predict the likelihood of disease progression based on factors such as disease stage, age, and genetic makeup. This information can be used to develop personalized monitoring plans and adjust treatment plans as needed.

Patient survival rates can be greatly increased and fatality rates can be significantly reduced by early detection and prediction of hematological malignancies. However, the nature of data on medical treatments is complex, necessitating a thorough study to uncover key explicative aspects and hidden data patterns. Utilizing AI is the only method for managing massive sets.


  • Software developed specifically for AI as a digital assistant for evidence-based medicine
  • No programming skills are required to use and train the AI
  • Offline Deep Learning training possible
  • User-friendly application interface
  • Results are objective, traceable, reproducible

The company HS Analysis GmbH works closely with the central laboratory in the Städtisches Klinikum Karlsruhe to obtain blood smears that can be used to develop deep learning models. This collaboration makes it possible to develop a deep learning model (HyperHaemaNet Model) capable of recognizing and classifying all mature peripheral blood cells.

The blood smears are prepared by the employees of the central laboratory and picked up by employees of the company HS Analysis. After the blood smears arrive at the company headquarters, they are automatically digitized using the HSA software. The fully automatic HSA scanner already integrated in the HSA software is used for this. The scanner has a slide stage on which the blood smears can be placed. The stage was specially developed by HS Analysis to be able to scan blood smears/tissue samples fully automatically. The stage is controlled by an algorithm that controls all three axes (X, Y and Z axis). Thanks to the developed auto-focus function, the stage can adjust the sharpness of the image at any time.

Digitalization of the slides

The digitalization of the slides is done with the software HSA SCAN, which was developed by the company HS Analysis GmbH. HSA SCAN turns physical slides into an digital file. Furthermore, the HSA SCANNER is used. This is a hardware product which upgrades an analog microscope to a digital microscope at low cost. The scan is performed with the Zeiss Primostar 3 microscope.

Software shows a section of the entire blood count so that the user can simply show different cell lines to the AI and thereby the AI learns these cell lines automatically.

  • Red: Erythrocytes
  • Light-Blue: Segmented Granulocytes
  • Purple: Lymphocytes

After the blood smear has been digitized, the ground truth data (GTD) is obtained. These are individual cells that are provided with a label (a class). This data is used to train the HyperHaemaNet Model. Based on evaluation metrics, the HyperHaemaNet Model is assessed at the end and, if necessary, improved.

Overall, the collaboration between HS Analysis and the central laboratory at the Städtisches Klinikum Karlsruhe is of crucial importance for the development of deep learning models for the detection and classification of cells in peripheral blood. The automatic digitization of the blood smears and the acquisition of ground truth data are important steps in developing a high-quality model, like the HyperHaemaNet Model.

Figure below shows a section of the HyperHaemaNet Model. In (a) you can see the blood cells before using the HyperHaemaNet Model. (b) shows the classification of the cells:

-Red: Erythrocytes

-Yellow: Thrombocytes

-Green: Leukocytes

The following results were achieved with the HyperHaemaNet Model based on the Vision Transformer Framework.

The HyperHaemaNet Model was trained in such a way that a further subdivision of the leukocytes is possible, as can be seen in figures given below. The subclasses of leukocytes can be divided into:

-Cyan: Segmented granulocytes

-Puple: Rod-nucleated granulocytes

-Orange: Monocytes

-Blue: Lymphocytes

With this further subdivision, all blood cells that occur in the peripheral blood of a healthy person can now be recognized and classified.

Most advanced instance segmentation for Haematology worldwide:

The software HSA KIT includes HyperHaemaNet, the most advanced instance segmentation for Haematology worldwide. HyperHaemaNet as deep learning technique was developed at HS Analysis GmbH and based on Vision Transformer (ViT).

In the software HSA KIT data scientists not only create and manage high quality ground truth data or train and manage corresponding deep learning models, they also are able to compare the models with metrics as well as overlays.


The effectiveness of algorithms for comprehending medical images is evaluated using a variety of measures. The table used to visualize algorithm performance and determine multiple assessment metrics is called the confusion matrix. Confusion matrices are used to evaluate deep learning models and give a more realistic view of their performance. The output could have two or more classes. In the table, there are four possible combinations of anticipated and actual values.

Mean Average Precision

Mean Average Precision (mAP) is a metric used to evaluate object detection models. Confusion Matrix, Intersection over Union (IoU), Recall, Precision are the sub-metrics that form the backbone of the formula for the mAP accuracy. The mAP is calculated by finding Average Precision(AP) for each class and then average over a number of classes.

Ground Truth Data used for HyperHaemaNet:

Used Data457924204762968152193

Validation of HyperHaemaNet

In the case of Loss, which is a function that requires to be decreased in order to have an ideal deep learning model. The loss value would produce a huge number if its predictions diverge too much from the actual results. The graph shows that the HyperHaemaNet which is based on ViT are 2,3 % after 18160 used GTD.

In the case of mAP, the accuracy of the instance segmentation detection is measured using mean average precision (mAP), another performance evaluation metric. Thus, the outcomes of instance segmentation will be more accurate the higher the mAP value. The graph also shows that the HyperHaemaNet based on ViT has superior mAP values being at 75 %.

Furthermore the HyperHaemaNet Model shows particularly good results for the outline of the cells (IoU = Intersection over Union).

Possibility to analyze further disease patterns with the HSA KIT

Nowadays, immunohematological markers are used to distinguish between blood leukemias.

There are various immunohematological markers used for the classification of leukemias. Here are some of the key markers:

  1. CD34: CD34 is a surface marker found on stem cells in the bone marrow and peripheral blood. High CD34 expression may indicate acute leukemia.
  2. CD13 and CD33: These markers are used in the diagnosis and classification of myeloid leukemias. CD13 and CD33 are myeloid antigens and are often analyzed in combination with other markers such as CD14, CD15, and CD64.
  3. CD19 and CD20: These markers are used in the classification of lymphocytic leukemias, especially B-cell leukemias. CD19 and CD20 are B-cell antigens and can help determine the type of leukemia.
  4. CD3, CD4, and CD8: These markers are used to differentiate between T-cell leukemias and B-cell leukemias. CD3 is a T-cell antigen, while CD4 and CD8 represent different subsets of T-cells.
  5. TdT: Terminal Deoxynucleotidyl Transferase (TdT) is a marker for immature precursor cells used in the diagnosis of acute lymphoblastic leukemias (ALL). High TdT expression indicates a tumor population composed of immature lymphoblasts.

These markers are analyzed in immunophenotyping using flow cytometry or immunohistochemistry to obtain information about the cell marker expression in leukemia cells and support the classification of leukemia. However, it is important to note that the specific selection of markers may vary depending on the individual case and the diagnostic criteria of the treating physician.

The further subdivision of leukocytes into the different disease patterns was not shown here, but it is also possible with the HSA KIT. By analyzing the CD markers with the HSA KIT, further clinical pictures can be classified such as e.g.:

-T-ALL: CD4 + CD8

-pre-B-ALL: CD10 + CD34

-AML: CD117 + myeloid marker

To start the analysis of CD markers in the HSA KIT, you just have to select which CD markers you want to analyze and load them into the HSA KIT by simply clicking on them.

Furthermore, it is possible to detect eosinophilia and basophilia with the HSA KIT. Eosinophilia often occurs in allergic reactions. Basophilia, on the other hand, often occurs in leukemias or parasitic infestations. In order to be able to use these two cell forms for your evaluation, it is possible to add them in the HSA KIT by clicking on the checkboxes.

In another deep learning model (HSA-CML-Paed-Module) the classification of chronic myeloid leukemia (=CML) cells has already started.

The HSA-CML-Paed module of the HSA KIT software for multiclinical studies in university clinics and reference centers is based on a neural network in which bone marrow and blood smears are annotated/analyzed and correlated with clinical parameters of the patients. In this context, the knowledge of still unknown pathomechanisms of CML in pediatric patients is obtained. All bone marrow and blood smears of a patient from the time of diagnosis up to the follow-up examination after one year (if the patient is still in remission) are used.

In the future, it will be possible to apply the HyperHaemaNet Model to other disease patterns, such as:

  • Benign Hematology – Differential Diagnoses
  • AML and MDS (5th WHO classification for morphological diagnosis)
  • Hereditary corpuscular anemia
  • T-cell lymphomas (diagnostic criteria and strategies, differential diagnosis)
  • (Neoplastic) Eosionophilia and combination to NGS
  • Effusion cytology
