Information for your tests
We recommend prior appointment for all the tests to avoid waiting period at the Centre. Appointment is a must for ultrasound or CT guided FNAC, Echocardiography, TMT, Holter, Executive Health check etc.
When to come empty stomach All ultrasound examinations of upper abdomen or whole abdomen require you to come empty stomach. This is essentially to see gall bladder in distended condition. However, practically, we are able to see it well in most of the patients and as a rule, we do not recommend empty stomach. But once in a while, if gall bladder is completely contracted, we may suggest you to come empty stomach again to have a better look at gall bladder.
When to come full bladder?
Generally all lower abdomen and whole abdomen examinations require full bladder. Also examinations of KUB and early pregnancy (generally up to 3-4 months) will require full bladder. Full bladder means you have to take lot of water at least 1-2 hrs before examination and not pass urine. A well distended urinary bladder helps in seeing uterus, ovaries and adnexa properly in females and prostate in males. It also helps in seeing small stones in bladder and ureters in KUB examination.
It is important to note that an urge to pass urine does not indicate you are having full bladder.
A really full bladder will make you uncomfortable. We need you to have full bladder, but you should be comfortable. For these examinations, come with some margin to wait as your turn may not come immediately on reaching clinic.
Examination of children
Examination of small children is difficult if they are crying. A well satisfied child is less prone to crying. We do not normally recommend them to be kept empty stomach except in some situations. Sometimes child may need to be sedated.
When you come in for your ultrasound examination for seeing the fetal well-being?
Drink 2 to 3 glasses of fruit juice/Water 20-30 minutes prior to the appointment unless otherwise ordered by your physician. We would like your baby to be awake during your exam for more thrilling experience. We would also like some fluids in your bladder to bring the baby's head out of the pelvis, but it does not need to be extremely full.
CT Scan Examination
Most of the examination will require administration of contrast. This is generally so when we suspect infective/inflammatory pathology or mass lesion. It is also administered for vascular studies and other special applications. Reports for kidney function such as blood urea, serum creatinine or any other investigation that may have been done for kidneys should be brought at the time of examination. Any history of diabetes and drugs that are being taken should be available.
CT Coronary Angiography
It is preferable to be fasting three hours prior to the test. Also one or two glasses of water one hour prior to investigation will give better results. Please bring all your relevant medical records such as any procedure done, creatinine and sugar levels and details of drugs being used. After the procedure, we advise you to again take 3-4 glasses of water in next 2 hours.
Upper abdomen and whole abdomen examinations
It is essential to come with overnight fasting for these examinations. Investigations will take 2-3 hrs or even more to complete as oral contrast is generally given and it takes time to reach colon. We normally do not ask patient to come with full bladder as it will generally fill during the course of administration of oral contrast. However, you are required not to pass urine during this examination. KUB and lower abdomen examinations There is no need of fasting for these examinations but full bladder is a requirement. Further, avoid examination immediately after taking food. A gap of 2 hrs is advisable whenever contrast is to be administered.
Normally no preparation is required for these examinations. But in case of children and those with neurological problems, may need to be sedated/anaesthetized as good examination can not be done, if patient is moving his/her head.
Allergy to drugs and contrast media
Though we use non-ionic contrast media which has very few reactions, however, a severe reaction is a possibility. If you are allergic to any drug or contrast media, you must tell us. This may require modification and different planning for examination.
Your Creatinine levels should be known.
If you are diabetic, then the history of the drugs you arer taking should be known
Upper/ whole abdomen examinations/MRCP
The precautions are same as for CT scan. You have to come empty stomach and no fluid such as water just before the examination.
KUB and lower abdomen examinations
Patient is required to be full bladder i.e. urinary bladder should be full.
Though in most of the examinations no contrast is used. But some will require administration of contrast. This is generally so when we suspect infective/inflammatory pathology or mass lesion. Some times it is also administered for vascular studies and other special applications. Reports for kidney function such as blood urea, serum creatinine or any other investigation that may have been done for kidneys should be brought at the time of examination. Any history of allergy to drugs, diabetes and drugs that are being taken for treatment should be available.
X Ray Examination
Generally no preparation is required for routine x-ray examinations. But x-ray of abdomen/ KUB/ LS spine will require you to have preparation previous night with charcol/unienzyme and some laxatives. Special x-ray investigations will required additional preparations and these will be given to you at the time of appointment itself.
Bone Densitometry & PFT
Do not require any preparations.
TMT, Echo & Stress Echo
