Gastric Tissue Biopsies and cultures are laboratory tests that examine stomach tissue. These tests are typically carried out to determine the cause of a stomach ulcers or other stomach symptoms. A Gastric Tissue Biopsy is the term used for the examination of tissue removed from the stomach. For a culture, the tissue is placed in a special dish to see if bacteria or other organisms grow.
Tissue samples from the stomach are obtained during an endoscopic exam. In this procedure, a long, flexible tube with a small camera (endoscope) is inserted down a patient’s throat and esophagus and into the stomach and upper small intestine (duodenum). With the endoscope, a physician can view a patient’s stomach for irregularities and remove tissue samples for a biopsy and culture. The samples are then analyzed for the presence of infections, signs of inflammation, and the presence of cancerous cells.
Urine cytology is a test to detect abnormal cells in a patient’s urine and is used along with other tests to diagnose urinary tract cancers. Urine Cytology is most often used to diagnose bladder cancer and can also detect cancers of the kidney, prostate, ureter and urethra. A physican may recommend a Urine Cytology test if blood has been detected in a patient’s urine (hematuria). A Urine Cytology test may also be used in patients who have already been diagnosed with bladder cancer and have undergone treatment. In these cases, the test may help detect a bladder cancer recurrence.
FISH Test: According to a recent article published in the Journal of Urology, laboratory testing (referred to as fluorescence in situ hybridization (FISH)) from a urine sample in patients with superficial bladder cancer may help predict a patient’s response to therapy, as well as their risk of developing more advanced disease. Patients who are at an increased risk of progressive cancer may wish to undergo more aggressive therapy.
Obstetrics and Gynecology
Colposcopy is a gynecological procedure that allows a physician to look directly at the cervix with a microscope in order to detect and examine abnormalities of the cervix. During a Colposcopy, tests (acetic acid wash, use of color filters, and sampling (biopsy) of tissues from the cervix) can be performed. Colposcopy is ordered if the result of a Pap Smear is abnormal or if the cervix appears visibly abnormal to the clinician performing the Pap Smear.
A Pap Smear, is a procedure to test for cervical cancer in women and involves collecting cells from the cervix. A Pap Smear can also detect changes in cervical cells that suggest the likelihood of cancer developing in the future. Our laboratories test multiple Pap Smear areas. Our Pap Ancillary tests include: HPV, CT, NG and TRICHOMONAS.
Bacterial Vaginosis is caused by a change in the balance of microorganisms found in a healthy vagina. A healthy vagina normally has many microorganisms in it. The microorganisms involved in bacterial vaginosis include Gardnerella, Mobiluncus, Bacteroides, and Mycoplasma. When bacterial vaginosis is present, these microorganisms increase in number, while the number of healthy microorganisms decrease.
|Skin Biopsy||A procedure where a sample of skin tissue is removed, processed and examined under a microscope. Results are usually are available in 3 to 10 days.|
|Abnormal||Noncancerous (benign) growths are seen. Benign skin changes include moles, skin tags, warts, seborrheic keratoses, keloids, cherry angiomas and benign skin tumors, such as neurofibromas or dermatofibromas.|
|Cancer cells such as basal cell cancer, squamous cell cancer or melanoma are present.|
|Other diseases such as lupus, psoriasis, or vasculitis are present.|
|A bacterial or fungal infection is present.|
There are three main types of Skin Biopsies:
- Shave Biopsy - outer part of the affected area is removed
- Punch Biopsy - a small cylinder of skin is removed using a punch tool
- Excisional Biopsy - an entire area of abnormal skin is removed
