What is paraffin embedded tissue?
Paraffin embedded tissue refers to a method of preserving tissue samples for examination and analysis in a laboratory setting. This process involves taking a small piece of tissue from a patient, usually during a surgical procedure or biopsy, and placing it in a fixative solution to prevent decay and maintain its integrity.
Once the tissue has been fixed, it is dehydrated by gradually replacing the water content with alcohol. This is followed by a series of steps involving the use of xylene, a clear liquid that helps remove the alcohol from the tissue. The tissue is then immersed in molten paraffin wax, which infiltrates and impregnates the tissue, ensuring its preservation.
After the tissue has been embedded in paraffin wax, it becomes solidified, forming a block. This block can be sliced into thin sections, typically 4-6 micrometers thick, using a device called a microtome. These thin sections are then mounted onto glass slides and subjected to a process called deparaffinization, which removes the wax.
The deparaffinized tissue sections are then stained with various dyes to highlight specific structures or cells of interest. This staining process helps pathologists and other medical professionals examine the tissue under a microscope and make accurate diagnoses.
Paraffin embedded tissue is commonly used in histopathology, a branch of medicine that involves the microscopic examination of tissue samples. It allows for detailed analysis of cellular and tissue structures, aiding in the diagnosis of various diseases, including cancer, infections, and inflammatory conditions. By preserving the tissue in paraffin wax, it can be stored for long periods of time and can be easily transported to different laboratories for analysis.
One of the main advantages of paraffin embedded tissue is that it allows for retrospective studies. This means that tissue samples can be stored for future research or reevaluation, even years after the initial diagnosis. This is particularly useful in cases where new information or technologies become available, allowing for a more accurate interpretation of the tissue sample.
Paraffin embedded tissue is also compatible with a wide range of laboratory techniques. Once the tissue has been sectioned and stained, it can be further analyzed using immunohistochemistry, molecular testing, or other specialized techniques. This versatility makes it a valuable tool in the field of diagnostic medicine.
In USA, there are several laboratories and hospitals that offer blood tests and diagnostic services that may involve the use of paraffin embedded tissue. It is important to choose a reputable and reliable facility that follows strict quality control measures to ensure accurate and reliable results.
When seeking blood tests in USA for diagnostic purposes, it is advisable to consult with a healthcare professional or specialist who can guide you in choosing the appropriate tests and procedures based on your specific condition or symptoms. They can also provide recommendations for reputable laboratories or hospitals that offer paraffin embedded tissue analysis.

How is paraffin embedded tissue prepared?
The process of preparing paraffin embedded tissue involves several steps:
- Fixation: The tissue sample is fixed in a formaldehyde solution to preserve its structure and prevent degradation.
- Dehydration: The fixed tissue is dehydrated by gradually replacing the water content with alcohol. This step helps in removing excess water, which can interfere with the subsequent steps.
- Clearing: The dehydrated tissue is then cleared using a solvent such as xylene or toluene. This step helps in removing the alcohol and making the tissue transparent, which is necessary for embedding.
- Infiltration: The tissue is infiltrated with liquid paraffin wax. The tissue is placed in a container filled with melted paraffin wax, which gradually replaces the clearing solvent. This step ensures that the tissue is completely impregnated with paraffin.
- Embedding: The infiltrated tissue is placed in a mold filled with molten paraffin wax. The tissue is oriented in the desired orientation and allowed to solidify. Once solidified, the paraffin block containing the tissue sample is ready for sectioning and analysis.

What preservation methods are used for paraffin embedded tissue in Tennessee?
Paraffin embedded tissue is a common method of preserving tissue samples for diagnostic purposes, including blood tests, in Tennessee. This preservation technique helps to maintain the structural integrity of the tissue, making it easier for pathologists to analyze and diagnose any underlying medical conditions.
In Tennessee, the preservation of paraffin embedded tissue involves several steps. Firstly, the tissue sample is fixed in a formalin solution, which helps to prevent decay and preserve the cellular structures. The fixed tissue is then dehydrated using a series of alcohol solutions, gradually replacing the water content with alcohol.
Once the tissue is dehydrated, it is immersed in a clearing agent, such as xylene, to remove the alcohol and make the tissue transparent. This step is important for allowing light to pass through the tissue during microscopic examination.
After clearing, the tissue is infiltrated with liquid paraffin, which replaces the clearing agent. The paraffin helps to support the tissue structure and protect it during the embedding process.
Next, the tissue is carefully embedded in a small container filled with molten paraffin wax. The container is then cooled, solidifying the paraffin and embedding the tissue within it. This creates a block of tissue that can be easily sliced into thin sections for microscopic examination.
To use the tissue for blood tests, thin sections are cut from the paraffin block using a microtome. These sections are then mounted onto glass slides and subjected to various staining techniques to enhance the visibility of cellular structures. Once the sections are prepared, they can be analyzed using a microscope to identify any abnormalities or indicators of disease.
It is important to note that the preservation methods for paraffin embedded tissue in Tennessee may vary slightly depending on the specific laboratory or facility. However, the general process described above is commonly followed to ensure the preservation and analysis of tissue samples for diagnostic purposes.
If you are in USA and in need of blood tests or any other diagnostic procedures that involve paraffin embedded tissue, it is important to consult with a trusted healthcare provider or laboratory. They will be able to guide you through the process and ensure that your tissue samples are properly preserved and analyzed to provide accurate and reliable results.
