Lithium Heparin Microtubes 100 Pieces 100 PCS

Lithium Heparin Microtubes are fundamental devices in the laboratory that allow safe, sterile and reliable collection of small blood samples. Each pack includes 100 test tubes, specifically designed to ensure practicality and precision in daily use. Thanks to the presence of lithium heparin, these microtubes prevent the blood sample from clotting and keep the chemical and cellular properties unaltered for all subsequent diagnostic analyses. They are designed to facilitate rapid transfer of the sample from the patient to the laboratory, with an airtight closure system that ensures the seal and preservation of the contents. The microtubes have compact dimensions, ideal for capillary, pediatric sampling or in conditions where the quantity of blood that can be withdrawn is limited. They are easy to handle and allow a significant reduction in the risk of contamination during the collection, transport and storage phases. Compatible with the main sampling and automated analysis devices, they make the activity of healthcare workers easier, more precise and safer.

The pack of 100 pieces guarantees a practical and economical solution for laboratories that need a continuous and reliable supply of microtubes. The regular use of these tubes promotes the standardization of laboratory procedures, allowing the traceability of each sample and compliance with the best safety and hygiene practices.

They are ideal for use in various healthcare contexts: hospitals, clinics, analysis laboratories and in all situations where immediate separation of plasma from whole blood is required to carry out biochemical analyses, hormonal tests or other clinical laboratory investigations.

Therapeutic Indications

Lithium heparin microtubes are indicated for the collection of blood from patients in whom the prevention of coagulation with heparin as an anticoagulant is necessary. They are mainly used in capillary blood sampling, particularly in pediatric patients, in subjects with difficult venous access, in newborns or in critically ill patients where the volume of blood that can be obtained and managed must remain minimal. They are suitable for the preparation of plasma intended for biochemical analyses, hormonal tests, renal, hepatic, hematological and metabolic function investigations where the presence of heparin as an anticoagulant is required compared to other substances. They allow rapid and safe sampling, offer certainty of sample quality and reduce the risk of accidental coagulation which could invalidate the analysis results. Their particular formulation also makes them fundamental for screening and periodic monitoring activities of pathologies that require precise and constant evaluation of plasma or serum values, offering healthcare professionals a reliable tool for optimal patient management.

Composition

Main constituents: the microtubes are made of transparent and resistant plastic material, suitable for contact with blood products and compliant with safety and quality regulations for medical devices. Inside them there is a calibrated quantity of lithium heparin, a form of heparin that effectively acts as an anticoagulant, preventing the formation of blood clots, preserving the physicochemical characteristics of the sample. The closing cap guarantees total airtightness and protection from external contamination, while the structure of the test tube is designed to be unbreakable and easily manipulated. The microtubes are free of latex and potentially allergenic agents, ensuring safety for both the patient and the operator. Additional excipients are exclusively those necessary for maintaining the structural integrity of the tube and the stability of the lithium heparin inside it, contributing to the high quality standard of the product.

Contraindications

The use of lithium heparin microtubes is not indicated in cases where it is necessary to obtain serum instead of plasma, or where specific laboratory tests require the use of other types of anticoagulants for the collection and storage of samples (for example EDTA or citrate). They should be avoided in all diagnostic or therapeutic protocols that explicitly exclude the use of heparin as an anticoagulant agent, or in the case of known hypersensitivity of the patient to heparin or other components of the test tube. In situations of collection of liquids other than blood, or for analyzes requiring different cell separation, the use must be carefully evaluated or avoided depending on the specific indications provided by the destination laboratory. It is important that healthcare personnel take care to verify the compatibility of the lithium heparin microtubes with the expected analytical methods, in order to guarantee the correctness of the results and the safety of the patient.

Safety of the drug for the species

Lithium heparin microtubes are medical devices subjected to rigorous quality and safety controls, designed to minimize any risk of contamination, exposure or unwanted interaction. Their use, if correctly carried out, is safe, both for the patient and for the healthcare worker in charge of the sampling. They are produced in certified and sterile environments, packaged in such a way as to guarantee the integrity of each unit, avoiding cross-contamination and alteration of the contents. The use of lithium heparin as an anticoagulant is widely recognized for its effectiveness and safety for clinical purposes, provided that the quantity and standards required by current legislation are respected. Furthermore, they have a minimal impact on the blood volume collected, making them particularly safe in children, newborns or fragile subjects, and do not present specific toxicity risks for humans if used according to instructions.

Precautions

Before use, it is essential to check the integrity of the microtubes packaging and the indicated validity date. The microtubes must be used exclusively by trained personnel, according to standard aseptic procedures in order to avoid any contamination of the sample. It must be ensured that each tube is filled correctly to the indicated volume to guarantee the correct blood/anticoagulant ratio, an essential condition to ensure the validity of the analytical results. It is recommended not to reuse microtubes, which are disposable and must be disposed of in accordance with biological waste regulations. During the handling and transport of the samples, maximum care should be taken to avoid breakages or losses. In case of accidental contact with skin or mucous membranes, wash immediately with soap and water. Do not ingest or inhale the contents of the tube. Keep out of reach of children and pets.

Method of administration

Lithium heparin microtubes are designed to be filled easily by capillary puncture, often using dedicated pipettes or integrated collection systems. The healthcare worker must carefully clean the sampling site, perform the puncture and collect the blood as quickly as possible to reduce the risk of microcoagulation. Once the test tube has been filled, it must be shaken gently to homogenise the blood with the anticoagulant and ensure correct preservation of the sample until analysis. The sample can then be stored at a controlled temperature according to the analytical indications, thus guaranteeing the maintenance of the integrity of the plasma components. After use, the microtube must be properly identified and sent immediately to the laboratory. In case of difficulty, do not insist on filling the same microtube to avoid the formation of clots and compromise the quality of the collected blood.

Treatment program

The use of lithium heparin microtubes is determined by the patient's clinical needs and the laboratory's requests for carrying out specific analyses. In hospital and outpatient settings, the blood collection program can be planned based on scheduled tests, ensuring rational use of the tubes according to daily, weekly or monthly needs. In chronic situations or patients with the need for close monitoring, the use of microtubes is programmed to allow frequent sampling without the risk of excessively lowering the patient's blood levels. Each test tube must be used exclusively for a single collection and always respecting the maximum time between collection and analysis to avoid deterioration of the sample. Correct management of the life cycle of the test tube, from purchase to post-use disposal, allows traceability and compliance with the safety standards required for medical healthcare devices.

Target species

The lithium heparin microtubes are intended for exclusive use on humans, with particular attention to all those situations that require a reduced blood sample or in which laboratory tests on small volumes of blood are necessary, as in the case of pediatric, neonatal, elderly patients or in subjects with vascular difficulties. Their selective use in the clinical and diagnostic field extends from clinical pathology departments to outpatient facilities, passing through the areas of intensive care, paediatrics, neonatology and mass screening.
