We offer a variety of testing services for patients and doctors. As a full spectrum laboratory dedicated to fulfilling the testing needs of the hospital, private physician practice and outpatient clinic, we are continually striving to provide the professional medical community with enhanced services.
Pathology Diagnostic Services
When drawing multiple tubes of blood, it is common for a specimen to get contaminated with anticoagulant from the previous tube. In order to prevent the specimen from getting compromised, it is essential to follow the correct order of draw.
Use the correct tube type for each test. Tests results are not valid if sample is drawn in an incorrect tube and switched to the correct tube.
When using a winged blood collection set for venipuncture and a coagulation (blue) tube is the first to be drawn, draw a discard tube (non-additive or a blue tube) first. Vacuum in the first tube is partially used up in drawing air from the collection set tubing, instead of blood, resulting in a partially filled tube. The discard tube is used to fill the blood collection set tubing with blood but the discard tube does not need to be completely filled. This step will ensure proper blood-to-anticoagulant ratio in the blue tube. You can use a no-additive (gold or yellow) or citrate (blue) tube as the discard tube.
Mount Sinai Clinical Labs offer a blood drawing service for patients who have been referred by their doctor. We prefer when you have a scheduled appointment; otherwise, we serve patients on a first-come-first-served basis, except in emergency situations.
Please come prepared by:
- Wearing sleeves that roll up
- Bringing a test order (requisition or prescription) completed by your doctor that contains diagnosis codes (ICD-10)
- Bringing your insurance card
- Fasting when required (e.g., for lipid profile and glucose tests)
If your doctor has requested a fasting blood test, this refers to the 10 to 12 hours before the blood test. Please do not:
- Eat food
- Drink anything other than water
- Chew gum (including sugar-free gum)
- Eat mints or cough drops
- Drink plain water
- Take prescribed medication, with water, before the test unless directed otherwise by your doctor. If you are on medications that are taken with food, or if you are diabetic, please seek advice from your doctor.
