Allergy - Alternaria Tenius Fungus Test

A lumbosacral spine X-ray is done by the lab technician on order from the doctor.
Lumbar spine consists of five vertebral bones and the thoracic spine also rests on the lumbar spine including:
Nerves
Large blood vessels
Cartilage
Tendons
Ligaments
Small amounts of radiation are used to take an image of your internal body. The X-ray helps the doctor in viewing if there is any internal injury, bleeding, abnormality or any disease affecting the bones.

General knowledge, you will need to remove any jewelry especially metallic items so they do not interfere with the rays. Inform your doctor, if you have any metal implants done. You have to wear a hospital gown so the quality of the X-Ray is maintained.

An X-ray is very useful for a lot of conditions. An X-ray gives a lot of information about your condition to your doctor like if you are suffering from chronic back pain or have had an internal injury. The X-ray can let the doctor evaluate your condition. A lumbar spine X-Ray is usually ordered if a doctor wants to see:
Any birth defect that is affecting your spine
Any injury or fracture on the lower spine
Any back pain that is more than four to eight weeks old
Check if you are suffering from osteoarthritis (joint arthritis)
Osteoporosis, a condition in which bones begin to become thin
Cancer, and
Abnormality in curvature or degenerative change in the lumbar spine
Other reasons for requesting of X-Ray by your doctor can be why you are suffering from back pain and for this your doctor can request one of the below tests as well:
CT Scan
Ultrasound
MRI Scan
Bone Scan
Each of these X-Ray scans provide a different image.

The X-ray is performed in either a hospital radiology department or a clinic or laboratory that specialize in taking X-ray, that are viable for a doctor's view. The typical way is of lying on the table face down. Then the lab technician moves a big camera over your body. A film is placed under the table below you in which the image is captured.

If needed your technician can ask you to lie in different positions like on your stomach, back, side and in some cases standing with your neck on one side, if requested by your doctor. When the image is being taken, you'll require to hold your breath and not move, as both affect the quality of the images.
