Introduction: the role of pre-treatment diagnostics
Pre-treatment diagnostics is a comprehensive assessment of the patient's condition before the start of any treatment or surgery. It is the basis of safe and effective medical care, as it allows you to identify risk factors, adjust therapy and prepare the patient physically and psychologically. In the practice of modern clinics, pre-treatment diagnostics combines laboratory tests, instrumental studies, functional assessments and clinical expertise. Its careful implementation gives Kharkiv patients confidence in the safety of procedures and helps doctors make informed decisions regarding anesthesia, surgical tactics or pharmacotherapy.
What is pre-treatment diagnostics and its main goals?
Pre-treatment diagnostics refers to a set of examinations and measures aimed at:
- identification of contraindications to planned treatment or surgery;
- assessment of the function of vital organs (heart, lungs, kidneys, liver);
- establishing baseline indicators for further monitoring;
- personalization of anesthesia regimen and drug treatment;
- patient preparation (prehabilitation) and rehabilitation planning;
- ensuring informed consent with documentation.
Who and when does pre-treatment diagnostics need to be performed?
The need and scope of pre-treatment diagnostics are determined individually, based on the type of intervention, the presence of concomitant diseases and overall risk. General categories of patients who require examination are:
- patients planning major elective surgeries (abdominal, cardiac, thoracic, and orthopedic surgery);
- patients before the start of oncological systemic therapy (chemo-/immunotherapy);
- persons with cardiopulmonary pathology, chronic kidney or liver diseases;
- elderly patients with sclerosis or signs of frailty;
- patients at increased risk of infections (before/after immunosuppression).
Basic methods of pre-treatment diagnostics
The standard approach combines laboratory tests, instrumental studies, and functional tests. Below is a detailed list with explanations of when and why each method is used.
Laboratory tests - what is included and what does it mean?
- Complete blood count (CBC) — evaluates the level of hemoglobin, leukocytes, platelets; important for detecting anemia, infection, or clotting disorders.
- Blood biochemistry — creatinine, ALT/AST, bilirubin, electrolytes; provides information about kidney and liver function, fluid and electrolyte balance.
- Coagulogram — prothrombin time, INR, APTT; necessary if there is a risk of bleeding or before operations with significant blood loss.
- Serological/virological tests — HBV, HCV, HIV; important when planning immunosuppressive therapy or invasive procedures.
- Special markers — tumor markers or immunological indicators according to individual indications.
Instrumental and functional studies
- Electrocardiography (ECG) — basic assessment of heart rhythm and ischemic changes.
- Echocardiography (EchoCG) — assessment of the pumping function of the heart and the valvular apparatus; recommended if cardiac disorders are suspected or if risk factors are present.
- Radiography and ultrasound — simple methods for assessing anatomy; ultrasound is safe and accessible for abdominal organs and vessels.
- CT/MRI — highly detailed methods for planning complex surgeries or evaluating tumors.
- Spirometry, endurance test (6-minute test) — assess respiratory function and exercise tolerance.
Functional assessment of anesthesia risk and frailty
Special attention is paid to the assessment of physical endurance (functional capacity) and frailty in elderly patients. Scales are used, the 6-minute walk test, the assessment of inhalation/exhalation endurance, as well as the frailty scale (Fried, Clinical Frailty Scale). The results influence the decision on hospitalization, the level of intensity of postoperative observation and the rehabilitation plan.
How pre-treatment diagnostics change the treatment plan
The results of the examinations allow:
- adjust drug doses (for example, depending on creatinine clearance);
- choose the type of anesthesia (local, spinal, general) taking into account the risks;
- postpone planned surgery for preliminary correction of the condition (treatment of anemia, stabilization of blood pressure, eradication of infection);
- determine the need for invasive monitoring or transfer to the intensive care unit after surgery.
Examples of clinical decisions dependent on diagnosis
- Patient with low hemoglobin - before major surgery, treatment of anemia (iron or erythropoietin) is recommended instead of immediate surgery.
- Detection of significant systolic cardiac dysfunction on EchoCG — revision of the anesthesia plan and possible postponement of the intervention until cardiac optimization.
- Viral markers are positive - the need for consultation with an infectious disease specialist and correction of the approach to sterility and prevention.
Table: Recommended set of tests depending on the risk of surgery
| Risk level | Type of operation (examples) | Basic set of tests | Additional tests |
|---|---|---|---|
| Low | Outpatient procedures, minor cosmetic surgery | ZAK, biochemistry (basic), ECG (by age) | Only necessary if clinically indicated |
| Average | Abdominal organs, orthopedics | CBC, biochemistry, coagulogram, ECG, ultrasound as indicated | Echocardiography, CT/MRI according to the surgical plan |
| High | Cardiac surgery, oncology operations, transplantations | Advanced biochemistry, coagulogram, serology, ECG, EchoCG, CT/MRI | Molecular profiling, specialist consultations, infection testing |
Practical advice for patients in Kharkiv
Planning a pre-treatment diagnostic requires attention to organizational and clinical aspects. Here are some things to help you prepare properly:
What to bring with you to your consultation/examination
- passport and identification documents;
- a list of current medications and a copy of prescriptions;
- medical record or discharge notes from previous hospitalizations;
- results of previous examinations (electronic or paper);
- contact details of the family doctor and/or specialists.
Preparing for tests - general rules
- fasting before biochemical tests (8–12 hours);
- inform your doctor about taking anticoagulants, antibiotics, hormones and dietary supplements;
- clarify whether you need to stop taking certain medications before the test;
- follow the instructions for preparing for CT/MRI (if contrast is required, check kidney function);
- If possible, write down questions in advance for during the consultation.
Time, cost and diagnostic packages
The timing of preoperative diagnostics depends on the set of tests: basic tests can be performed in a few hours, while molecular testing or special studies can take from a few days to two weeks. Many clinics in Kharkiv offer ready-made preoperative diagnostic packages, which simplifies patient logistics and can be more cost-effective than individual tests.
| Package type | What does it include (example) | Duration of results |
|---|---|---|
| Base | ZAK, biochemistry, coagulogram, ECG | 2–24 hours |
| Expanded | Ultrasound, Echocardiography, CT scan (according to indications), consultations | 1–5 days |
| Oncological | Molecular profiling, tumor markers, PET/CT — as needed | 7–21 days |
Specific areas of application
Oncology: the role of molecular profiling
In oncology, pre-treatment diagnostics include molecular testing of the tumor, which allows for the selection of targeted or immunotherapy. Decisions are based on markers such as EGFR, ALK, PD-L1, RAS/BRAF, etc. Such testing increases the effectiveness of treatment and reduces chemotoxicity due to a targeted approach.
Cardiological risks and preoperative assessment
Patients with cardiovascular disease require a detailed cardiac evaluation—ECG, echocardiography, laboratory markers (troponins if suspected). Recommendations for testing and preparation are often based on international guidelines, including NICE (see guidance on the website NICE).
Pediatric and gynecological context
For children and pregnant patients, the approach to pretreatment diagnostics is special: the risks of radiation exposure, pharmacokinetic features, and safety of fetal development are taken into account. When planning interventions in pregnant women, consultation with an obstetrician-gynecologist and special protocols are required.
Advantages of a systemic approach based on local practice
In Kharkiv, patients can benefit from comprehensive packages in private clinics that combine diagnostics, consultations, and rehabilitation. Examples of information about such services are the clinic's portfolio and case studies available online (see MILNER MEDICAL portfolio), which helps patients assess the quality of services.
If you are looking for information about additional procedures (e.g. infusion therapy) in the region, reviews of local services will be useful, such as: Droppers in Kharkiv region: 6 best places to get them.
Risks of over-testing and principles of a rational approach
Over-testing leads to unnecessary costs, unnecessary anxiety, false positives, and the possibility of unnecessary invasive procedures. The guiding principle is to only test when the results will change clinical management (“the test should impact management”). Organizations such as Johns Hopkins Medicine and international campaigns such as Choosing Wisely emphasize the need for targeted testing.
How to avoid unnecessary tests - tips for patients
- Ask to be explained exactly how the test result will affect the treatment plan.
- Ask about alternatives and possible risks of the examination itself.
- Find out if the tests can be combined into one day for convenience and time saving.
Legal and ethical aspects
Documenting the informed consent process and test results is key to reducing medico-legal risks. Informed consent should describe the purpose of the tests, possible risks, alternatives, and consequences of refusing testing. Clinical protocols should be transparent and comply with national legislation and international standards.

Tips for choosing a clinic in Kharkiv
When choosing an institution, pay attention to:
- availability of licenses and certifications;
- qualifications and reviews of specialists;
- availability of modern equipment and the possibility of comprehensive service;
- the opportunity to receive a preoperative diagnostic package and rehabilitation plan.
Examples of local resources and portfolios of work help you make a decision: see before/after examples and service descriptions in MILNER MEDICAL portfolio and details on specialized surgeries, for example in the article on plastic surgery (see Genital plastic surgery in Kharkiv).
Perioperative rehabilitation - what does it give?
Prehabilitation is the preparation of a patient for surgery that includes physical exercise, nutritional optimization, chronic disease management, and psychological preparation. Studies show that patients who undergo prehabilitation have fewer complications and a shorter postoperative recovery period. Clinics that offer a comprehensive approach often integrate prehabilitation into preoperative preparation programs.
Technology and innovation: telediagnostics and digital solutions
Telemedicine allows for partial pre-consultation, history taking, and discussion of examination plans, which saves the patient time. Electronic medical records and integrated systems reduce the risk of losing results, improve information exchange between specialists, and speed up consultation decisions.
Where to find additional information and authoritative sources
For in-depth study of the topic, it is recommended to refer to official sources and guidelines:
- NICE - guidelines on preoperative assessment and optimization (see NICE Guidance).
- Johns Hopkins Medicine — practical materials on tests performed before surgery.
- CDC/WHO infection control and PEP protocol recommendations (see CDC).
