Procedures

Chest X-Ray

• Diagnostic procedure that produces images of the lungs, airways, heart, and bones.

• Used to diagnose: pneumonia, tuberculosis (TB), fluid buildups around the lungs, lung cancer, and collapsed lungs.

• Advised when a patient exhibits symptoms such as a recurrent cough, chest discomfort, shortness of breath, or fever.

• Obtains a clear picture of the lungs and determine whether there are any infections, abnormalities, or impairment within the chest area.

• Can also be used to track the progression of specific diseases or to determine how effective a treatment is.

• Quick and easy to undergo, typically lasting only a few minutes. The patient may stand or lie still while the imaging device takes photos with a low dosage of radiation.

• Provides a decent summary and can assist additional tests or therapy as needed.

Sputum GeneXpert

• A specialized laboratory process used to detect Mycobacterium tuberculosis, the bacteria that causes tuberculosis, as well as to assess whether the bacteria are resistant to rifampicin.

• Advised if a person has pulmonary tuberculosis symptoms like chronic coughing lasting more than two weeks, fever, coughing up with blood, sweating at night, and unusual loss of body weight.

• A person sends a sputum sample and then gets put in a cartridge and introduced into a machine that analyzes the existence of tuberculosis DNA.

• The results are usually ready in under two hours.

• GeneXpert is more trustworthy than traditional sputum tests because it can detect the existence of tuberculosis and resistance in a drug fast and correctly.

• Enables physicians to begin the appropriate therapy right away and aids in the prevention of the spread of resistant forms of TB.

Urinalysis

• A common diagnostic test that examines the content, concentration, and appearance of urine.

• Used to detect and monitor a wide range of conditions such as urinary tract infections, kidney disease, diabetes, and even dehydration.

• Includes three main components:

  • A physical examination to observe the urine's color and clarity.

  • A chemical analysis using dipsticks to detect substances like glucose, protein, ketones, blood, or pH imbalance.

  • A microscopic examination to look for cells, crystals, bacteria, or casts that can indicate specific health issues.

• Provides valuable information about a person’s overall health.

Fecalysis

• Also known as stool examination, is a laboratory test that analyzes a person's feces to help diagnose conditions affecting the digestive tract.

• It involves checking the stool’s physical characteristics like color, consistency, and presence of mucus or blood; performing a chemical analysis to detect substances such as hidden (occult) blood or excess fat; and conducting a microscopic examination to look for parasites, their eggs, bacteria, fungi, or undigested food particles.

• Commonly used to identify infections, gastrointestinal bleeding, malabsorption disorders, and inflammatory conditions like colitis.

• A crucial test in evaluating symptoms such as diarrhea, abdominal pain, and unexplained weight loss.

PT (Prothrombin Time)

• A blood test that measures how long it takes for blood to clot.

• Evaluates the function of certain clotting factors, specifically those made in the liver and dependent on vitamin K.

• Often used to check for bleeding disorders, monitor patients on blood-thinning medications like warfarin, and assess liver function.

• A prolonged PT may indicate conditions such as liver disease, vitamin K deficiency, or the presence of anticoagulants.

• The result is typically reported in seconds and may also be expressed as an International Normalized Ratio (INR) to standardize results across different labs.

Partial Thromboplastin Time

• A blood test that measures how long it takes for blood to clot, specifically assessing the intrinsic and common pathways of the coagulation cascade.

• Helps evaluate the function of various clotting factors, such as factors VIII, IX, XI, and XII.

• Commonly used to detect bleeding disorders like hemophilia, monitor patients receiving heparin therapy (an anticoagulant), and identify clotting factor deficiencies or the presence of inhibitors that affect clotting.

• A prolonged PTT can indicate conditions such as liver disease, vitamin K deficiency, or the presence of autoimmune inhibitors like lupus anticoagulant.

Cranial CT Scan

• A diagnostic imaging procedure that uses X-ray beams and computer processing to produce detailed cross-sectional images of the brain.

• Commonly used to assess head injuries, brain tumors, hemorrhages, and neurological symptoms.

• The patient being instructed to remove any metal objects, such as jewelry.

• If contrast dye is required, the patient may need to fast for a few hours prior.

• The patient then lies on a motorized table that slides into a large, doughnut-shaped CT scanner.

• To ensure accuracy, the head is immobilized, and the scanner rotates around the patient, capturing multiple images.

• If contrast is used, patients are monitored afterward for any allergic reactions or adverse effects.

RT-PCR (Reverse Transcription Polymerase Chain Reaction for COVID-19)

• A molecular diagnostic method used primarily for detecting the RNA of viruses such as SARS-CoV-2, which causes COVID-19.

• The procedure involves collecting a nasopharyngeal or oropharyngeal swab sample, which is then sent to a laboratory.

• In the lab, the viral RNA is converted into DNA through reverse transcription, then amplified using the polymerase chain reaction process to identify the presence of the virus.

• This test is highly sensitive and specific, making it the gold standard for confirming active COVID-19 infections.

• Proper technique during sample collection is critical to avoid false negatives, and appropriate infection control measures must be followed during and after the procedure.

Blood Typing Test

• A laboratory procedure used to determine a person's blood group.

• It identifies the specific antigens (proteins and sugars) present on the surface of red blood cells (RBCs) and the antibodies present in the plasma.

• The two main blood typing systems are:

  • ABO System: This system classifies blood into four main types: A, B, AB, and O, based on the presence or absence of A and B antigens on the RBCs.

  • Rh System: This system determines whether the Rhesus (Rh) D antigen is present (+) or absent (-) on the RBCs, resulting in Rh-positive or Rh-negative blood types.

• Forward Typing: The individual's red blood cells are mixed with antibodies against A and B antigens. If the red blood cells clump together (agglutinate), it indicates the presence of that specific antigen on the cells.

• Reverse Typing (Back Typing): The individual's plasma is mixed with red blood cells of known type A and type B. If agglutination occurs, it means the plasma contains antibodies against that specific blood type.

• Rh Typing: The red blood cells are also tested for the presence of the Rh D antigen. If the cells agglutinate when mixed with anti-Rh D antibodies, the person is Rh-positive. If there is no agglutination, the person is Rh-negative.

Sputum GS CS

• A sputum gram’s stain is a laboratory test that allows your doctor to diagnose a bacterial infection in your respiratory tract.

• It’s the most common preliminary test beyond a chest X-ray for pneumonia and other respiratory infections, and can help your doctor promptly prescribe a treatment plan.

• A portion of the sputum sample is placed onto different types of culture media in petri dishes or other containers. The culture media are incubated at a suitable temperature and for an appropriate time to allow any bacteria or fungi present to multiply and form visible colonies.

• Once growth occurs, the colonies are examined to identify the type of microorganism based on their appearance, growth patterns, and biochemical tests.

• For sensitivity testing (if bacteria are grown), different antibiotics are added to the culture media. The lab technician observes whether the bacteria can grow in the presence of these antibiotics.

• The results are usually reported as "Susceptible" (S), "Intermediate" (I), or "Resistant" (R) for each tested antibiotic.

Chest CT Scan

• A diagnostic imaging test that uses X-rays and computer processing to create detailed cross-sectional images of the lungs, heart, airways, blood vessels, bones, and soft tissues in the chest.

• The patient lies on the table that slides into the CT scanner and must remain still that usually last for 5-10 minutes.

• It is used for diagnosing lung diseases such as pneumonia, TB, emphysema, and also lung cancers or tumors, assesses pulmonary embolism or blood clots, monitoring chronic lung conditions, evaluating chest pain, injuries and infections, and in guiding biopsies.

• There are various types of it, such as the standard Chest CT, a High-Resolution CT to assess interstitial lung disease, CT Pulmonary Angiography in pulmonary embolisms, and Low-
